Match the energy source to the site
Solar exposure, ground conditions or biomass fuel access shape what is practical.

Renewable heat sources
Heat sources grouped by the energy behind the system.
Solar, geothermal or biomass sources can be used depending on the site, project load and preferred energy strategy.
The decision starts with the renewable source, then moves into storage, controls and heat delivery design around the project load.

01
Solar Heating
Evacuated tube solar hot water and solar heating support for homes, pools and selected hydronic projects.
02
Geothermal
Ground-source heating, cooling and hot water systems based on stable underground temperatures.
03
Biomass Heating
Wood, pellet and biomass boiler systems that can support heating and domestic hot water loads.
Design considerations
Renewable heat is a source decision and a system design task.
Design the energy source, storage, emitters and controls together so their temperatures, capacities and operating sequence are compatible.
Load
Define the heating demand
Domestic hot water, pool heating, space heating and commercial loads need different strategies.
Storage
Store heat where needed
Tanks, buffers and thermal storage can be critical for renewable heat source performance.
Backup
Plan boosting and resilience
Solar and biomass systems may need backup, boosting or hybrid arrangements depending on demand.
Controls
Coordinate source and delivery
Controls help decide when the renewable source, backup source or storage should operate.
Integration
Connect to the heating system
Hydronic emitters, hot water storage and pool systems need compatible temperatures and hydraulics.
Renewable options
Renewable choices depend on the energy source and system load.
| Renewable source | Best suited to | Planning notes |
|---|---|---|
| Solar heating | Domestic hot water, pool/spa support and projects wanting solar contribution to heating loads. | Household usage, roof pitch, collector orientation, storage and boosting strategy need review. |
| Geothermal | Heating, cooling and hot water projects where ground-source energy can be integrated. | Ground loop feasibility, site conditions and system integration are early design questions. |
| Biomass | Projects considering wood, pellet or boiler systems for heating and hot water loads. | Fuel supply, storage, emissions, flue design and hydronic integration need project-specific review. |

FAQ
Common questions.
What lower-carbon heat options does SmartHeat reference?
SmartHeat supports solar, geothermal and biomass options, each with different source, storage and system integration requirements.
Can renewable sources support hydronic systems?
Yes. Lower-carbon heat sources can support hydronic or hot water systems when the temperature, storage and controls are properly designed.
Which option is best?
It depends on site conditions, load type, energy availability, plant space, maintenance expectations and whether the project needs heating, cooling or hot water.
Should these systems be planned early?
Yes. Roof area, plant space, ground works, storage, fuel access and system controls can all affect feasibility.
