It covers the whole demand
Both space heating and hot water. That is what separates it from a stove, which only contributes.
All energy measures
Heating and hot water
Biomass boiler
A biomass boiler heats the entire waterborne system, hot water included. Unlike a stove it is a main heat source, not a supplement.
See what this means for your homeThis measure is relevant if
- The home has waterborne heating
- The heat demand is large enough to carry the investment
- There is room for both the boiler and fuel storage
- You want to replace electricity or oil as the main source
What it does to energy use
Storage is the practical limit
Pellets need a silo or store room, and logs need dry storage. Space decides this more often than economics do.
Efficiency falls at part load
A boiler oversized for the demand runs in short bursts. Efficiency then drops, and fuel consumption rises more than the heat demand would suggest.
It needs attention
Ash has to come out, fuel has to go in, and the plant needs servicing. That is an operating job a heat pump does not have.
Sequence matters
The boiler is the main heat source and is sized to the heat demand. It therefore belongs after everything that changes that demand — envelope, windows and ventilation — just like a heat pump.
Enova funding
Biomass boilers are among the measures Enova funds.
Rates and terms change. What you can receive depends on the building, how the work is carried out and which schemes apply at the time. Always check Enova's own pages before relying on a figure.
The rates tell you what you can receive. The calculation tells you what the measure actually does to your home — how much it saves, what it costs, and whether it should come before or after the others.
