What to heat ? Heat pump or biomass boiler?

 

What to heat ?  Heat pump or biomass boiler?

 

How to heat effectively and cheap ? This question is asked by many customers these days. Currently, as part of the fight against smog, there are many heating devices that can be purchased with an additional payment not only for their purchase but also for installation.

 

The subsidized heating devices are primarily heat pumps and biomass-fired central heating boilers. These are currently two popular heat sources on our market. Which device to choose?

 

A heat pump is not for every building.

It is enough to read on the Internet or watch many videos on YouTube to see that not every building can be effectively heated by a heat pump. Heat pumps work best in modern, passive, well-insulated buildings with a low-temperature heating system. An additional advantage is the lack of the need to build a chimney, which saves a few thousand euro on installation costs.

If we have a building with a high demand for heat, poorly insulated with an outdated, old-type heating system, the choice is not so obvious.

And if the roof of our building prevents the installation of a photovoltaic system, then the choice should definitely fall on a modern heating boiler. Heat pumps require a properly designed heating system and, contrary to popular belief, it does not have to be only a floor system, because it can also be radiators. Radiators, however, then must be properly oversized and selected so that they can work on a low parameter, i.e. on a low supply water temperature. In the absence of a proper installation and proper insulation of the house, it is worth investing in a decent and solid heating boiler.

 

Biomass is still widely available as much as cheaper fuel on the market.

Taking into account the co-financing for the purchase and installation of a biomass boiler, e.g. for pellets or wood, it is certainly a device that is still an interesting alternative to heat pumps. It should also be remembered that if the user has his own biomass resources, e.g. he has his own energy plantation forest, orchard or straw bales, then using a biomass heating boiler he has practically free heating. However, a heat pump is still the use of electricity for heating, which means that we are energy dependent on state-owned companies and electricity distributors. Unfortunately, the current tariffs and solutions regarding the purchase of electricity from photovoltaic installations do not guarantee 100% energy security for the user of such an installation.

 

Which biomass central heating boiler to choose?

When choosing a biomass heating boiler, it is worth considering the availability of a given fuel in the area and answering the question whether I will use fuel from my own resources or buy it on the market. Biomass fuels that we can obtain on our own and thus heat a house or a company completely free of charge are, for example, wood and wood waste, wood chips, sawdust or bales and straw briquettes. Pellet is a popular fuel around the world and widely available, but you have to remember that when using sawdust pellets and buying it on the market, we are completely dependent on producer prices. Therefore, an interesting solution are combi-type hybrid heating boilers in which you can burn both wood and pellets, e.g. Sigma Dual. A hybrid boiler with automatic fuel feeding is also the Biowarmer series, which can burn pellets, wood chips and briquettes.

 

Gasified wood boilers are still an economical choice.

Gasified wood central heating boilers are also subsidized for purchase and installation as part of the clean air programme. Thanks to the pyrolysis technique, we have clean wood burning and if someone has access to their own raw material or can buy wood at an attractive price, it is still the cheapest heating on the market, which also gives its user 100% energy independence. It is therefore not surprising that wood gasification stoves are still a popular source of heat throughout Europe.

 

Bivalent or hybrid boiler rooms are still an interesting solution for undecided users.

As we wrote earlier, heat pumps use electricity, which means we are still dependent on the prices of energy carriers and the policy of electricity distributors. Biomass - especially from own resources, gives much greater energy security and independence. Therefore, undecided customers often choose bivalent or hybrid boiler rooms, i.e. those that are powered by two or more heat sources. Such a popular solution is a heat pump with a pellet stove or a compact Slim boiler for pellets. Such a pellet stove, built with a burner and a basket, takes up little space and will fit even in a small boiler room with a heat pump.
