Space heating

Most companies and homes heat with gas. This is a fossil fuel and emits CO2. Saving energy to heat rooms and water can therefore be very beneficial for the environment. It can also be great for your wallet. Gas costs usually account for about 2/3 of the total energy bill. In addition, the energy tax for gas will increase, while for electricity, it will decrease. So it's smart to look for alternatives to the gas-fired central heating boiler.

Solar thermal roof

A solar thermal roof is actually a combination of solar panels and a solar boiler. This PVT roof produces hot water and electricity from solar energy. Panels on the roof convert sunlight into electricity and ensure that solar heat is exchanged with water in the storage tank inside. The heated water can be used for tap water and for heating your building with the help of a heat pump.

  • Produces both hot water and electricity and thus saves space
  • Available as a separate panel or as a roof element with integrated insulation
  • Suitable for flat and pitched roofs
  • Saves energy
  • Also functions on cloudy days
  • The shorter the distance between collector and boiler, the higher the efficiency
  • This is a relatively costly investment
  • Space required for boiler, storage, buffer and/or boiler vessels
  • Have the load-bearing capacity of the roof checked before installation
  • Take into account the weight of the boiler vessel relative to the strength of the supporting structure
Regulations

Monumental

  • A permit is required: customized advice is necessary.
  • The advice takes into account the historical value of the existing roof covering.
  • In many cases possible on building parts without monumental value or at monuments provided that the appearance of the monument is not damaged.
  • Sometimes possible on a monument, on roofs where the solar collectors are not visible from any side from the ground.

Protected city view

  • Buildings without monument status in the protected cityscape, characteristic and / or iconic buildings are subject to stricter aesthetics supervision and, according to most zoning plans, may not be changed without a permit. Make sure that the sustainability measures do not make changes. If this is the case, a permit may be required. The points of attention as stated for monuments also apply here in most cases.

Air heat pump

An (electric) air heat pump extracts energy from the outside air which can be used for heating tap water and for space heating. Electricity is used instead of gas. It is possible to go all-electric or install a hybrid system. In a all-electric system, the heat pump, in combination with a buffer tank, generates all the necessary heat for both heating and domestic hot tap water. You can also opt for a hybrid heat pump, whereby the heat pump only generates heat if it is above 4˚C outside. The all-electric heat pump only works in combination with a low-temperature delivery system, such as underfloor heating. It is important that your building is well insulated before you consider switching to low-temperature heating and a heat pump.

The air heat pump has an outside element and a smaller interior element. The outside element can be placed at various locations outside the building, taking into account possible noise production (not near windows) and whether the outside element is visible from the public space. The interior element is placed next to the boiler together with the buffer tank.

  • Very sustainable
  • Highly efficient system
  • No ground source required
  • Low-temperature heating and good insulation required
  • Good positioning is important to prevent noise nuisance
  • Keep sufficient distance around the outdoor unit
  • The indoor and outdoor units can be placed at a maximum distance of 45 metres apart
  • With an all-electric heat pump, correct dimensioning by means of heat loss is very important
  • It may be necessary to upgrade the electricity connection, there are costs associated with this

Monumental

  • The outdoor unit is not permit-free; tailor-made advice is necessary.
  • The installation must not be visible from the public space.
  • The system may not cause damage to (structural) monumental parts.

Hybrid heat pump

If the heat demand is so high that it is not possible to heat with just a heat pump, a hybrid heat pump offers the solution. If it is really cold outside, below 5 degrees Celsius, it is difficult for the air heat pump to extract heat from the outside air. In the case of a hybrid heat pump, a gas-fired boiler will then switch on. Ask the installer whether your existing central heating system is suitable for this or opt for a new system with a heat pump and central heating boiler in one. The hybrid heat pump also uses a central heating system to heat tap water, so no buffer tank is required. It is also not necessary to switch to low-temperature heating, such as underfloor heating. Insulation and ventilation are required because otherwise, electricity consumption will become too high. For this reason, it is also interesting to explore whether you can combine the heat pump with solar panels. Most of the year, the heat pump will be in operation, which will save a lot of gas. And the costs of a hybrid heat pump are lower than those of other heat pump systems.

Keep in mind that air heat pumps have an external part. These must be carefully placed due to noise production, for example not near windows. It is possible to place a casing around the external part for noise insulation.

  • Sustainable and efficient energy source
  • Is also able to ensure cooling in summer (depending on the type)
  • No ground source required
  • Lower investment than for an all-electric heat pump
  • Relatively limited impact on building and user
  • Have the installer adjust when the central heating is switched on, indicating what you think is important, saving more gas or heating as economically as possible
  • Although the delivery system does not always need to be adjusted, low temperature dispensing will lead to the highest efficiency
  • This is always work for a professional installer
  • Good insulation is required
  • Good positioning is important to prevent noise nuisance
  • The indoor and outdoor units can be placed at a maximum distance of 45 metres apart

Solar heat pump

Heat pumps can extract heat from various sources. Well-known sources are air, soil and water. A less known source is solar heat. PVT (Photo-Voltaic-Thermal) panels or solar collectors can be used to extract solar heat and ambient heat. The absorbed heat is then increased by the heat pump for low-temperature heating. A solar heat pump is particularly suitable for buildings with a large roof surface area. A large absorption surface area is required to extract enough heat even on cloudy days. Cooling is only possible at night with this system.

  • Saves energy
  • No noise production
  • Can be integrated with panels for electricity generation
  • The panels can be aesthetically concealed in the roof surface
  • This is a relatively costly investment
  • Low-temperature heating and good insulation required
  • Not always allowed with historically valuable properties
  • Have the load-bearing capacity of the roof checked before installation
  • Take into account the weight of the boiler vessel relative to the strength of the supporting structure

Ventilation heat pump

A ventilation heat pump is an interesting solution for large buildings where there is no balanced ventilation yet but there is mechanical extraction. The ventilation heat pump extracts heat from the extracted ventilation air and brings this heat into the central heating system, thus saving energy and lowering your energy bill. The ventilation heat pump is installed in the place of the existing ventilation box. The capacity of this type of system is usually low, which is why this system is often used in a hybrid setup with a central heating boiler.

  • Replaces the mechanical ventilation box
  • Reduces gas consumption
  • Strongly dependent on the amount of air that needs to be refreshed
  • Good insulation is recommended
  • Ventilation box should not be placed too far from the central heating boiler

Ground source heat pump

A ground source heat pump uses thermal energy from the ground. At 55 to 100 metres below ground level, the constant ground temperature of 12 °C is extracted with a heat exchanger. A heat pump increases this thermal energy to a suitable temperature for low-temperature heating, maximum 55 degrees. A ground source is most suitable if you also use it to cool the building, for the purpose of regenerating the ground source over summer. This heat pump requires good building insulation, ventilation and possibly a new form of heating in your building, such as underfloor heating. The investment is higher than with an air source heat pump, especially because of the construction of the ground source. Keep in mind that you need a permit for this and that the garden must be accessible. With monuments, this can often be challenging.

Is your foundation in need of replacement? It is possible to use a foundation pile as a vertical ground exchanger. To convert the ground energy into heat, a heat pump is then connected. This eliminates the need to build a separate ground source, thus saving you considerable investment costs.

Considerations

Did you know that there are different types of ground sources? Closed and open sources. Make sure you are properly informed. Closed sources are possible horizontally, vertically and in surface water. Open sources are available in mono, recirculation and doublet versions. The latter is also called thermal energy storage.

Ground-coupled heat exchanger

A ground-coupled heat exchanger is basically a storage for heat (or cold) deep in the ground. The system lies between 55 and 100 metres below ground level, and uses the constant ground temperature of 12 degrees Celsius. In summer, this temperature can be used to cool. In winter, 12 degrees Celsius is relatively warm and can therefore heat the water. A heat pump increases the temperature to make it suitable for low-temperature heating. A ground-coupled heat exchanger system is particularly suitable for heating at a district level or for large buildings. In other situations, such as for a residential home, an ordinary heat pump with a ground source is more suitable.

Condensing boiler

Most people opt for a Condensing boiler when their old central heating boiler needs replacing. On average, a boiler will last fifteen years, during which time boilers will have become more energy efficient. Modern condensing boilers use condensation heat and can therefore achieve a high efficiency. In addition, modern boilers can modulate and are better adjustable, so that they do not run at full speed with a small heat demand. With a new boiler, you can save up to 20% on the gas bill, which means you earn back your investment within a few years.

Pellet boiler

An alternative to an open fireplace or an ordinary wood-burning stove is a pellet stove. The pellet stove only heats the room in which the stove is located. There is also a central heating pellet stove, which is a variant of the pellet stove that can be connected to the central heating system, such as the boiler or a buffer tank for hot water. The central heating pellet stove can therefore heat water for several rooms. The fuel of a (central heating) pellet stove consists of wood pellets, which are small rods of sawdust and wood waste, a cheaper fuel than gas. The pellet reservoir will need to be refilled regularly. For both variants of the pellet stove, place a particulate filter in the chimney or flue gas duct to capture particulate matter.

  • Emits less particulate matter than a fireplace or ordinary wood burner
  • Saves energy through efficient heating
  • The fuel is a natural raw material with a low CO₂ footprint, provided it is of good origin

Setpoint and night-time reduction

Setpoint and night-time reduction

Heating systems are only set properly if they are adjusted to all available internal and external heat sources, such as people, lighting, computers and the sun. Night-time reduction is one of the resulting measures. With night-time reduction, the temperature is lowered. This ensures that there are no large fluctuations, and therefore large peaks, in the system. Especially for larger buildings, it is useful to set a setpoint and a night-time reduction. This allows the entire building to be set correctly at once (although preferences can still be adjusted manually). The lighting and heating/cooling will be lowered or switched off during absence and this can save a lot of money and energy!

Innovation
Hydrogen boiler

Hydrogen boiler

As an alternative to the gas boiler, the hydrogen boiler is emerging. In this new boiler, hydrogen is used for the generation of hot tap water and central heating water. The big advantage of this system is that this is done at a high temperature (so no extensive building insulation values or low temperature heating is required) and the residual product consists of water. This makes the hydrogen boiler itself a sustainable replacement of the gas boiler. An important side note is that hydrogen is produced on a large scale from natural gas. The alternative production method, electrolysis, is not yet widespread and also very inefficient. Transport is also not optimal yet. Distribution ideally goes via the existing gas pipelines, but up to now the hydrogen has to be supplied in tanks. Finally, it is difficult to predict when and whether hydrogen will become accessible for home use. The use of hydrogen boilers has so far been limited to a few pilots.

Ground source heats the facade

Ground source heats the facade

A technique that has been used since 2011 for energy savings in heating is the active insulation of exterior facades. This involves pumping heat from the ground of approx. 10-12˚C to heat the exterior walls. This heat is further heated to 20˚C in winter by a heat pump. The existing heating can be retained. In summer, the 10-12˚C water is used for cooling. The system can be applied to the exterior or interior facade with prefabricated elements, in which the piping is pre-installed.
