A very efficient method to heat a room space.
Using Natural Gas Condensing Boilers or Hot Water Heat Pump systems (HPHW) as the heat sources makes hydronic heating cost-effective and efficient in operation. It is possible to do a large solar design for heat input, however would require a pool to use leftover heat in summer.
These modern heat source systems are quite easily retro-fitted to homes that have an outdated heat source but have a good quality underfloor heating system in place. There are a lot of homes set up by the now extinct Solar 60 company with underfloor heating and trying to work off a tiny solar system. These homes are using straight electric power from the HWC to heat their floor pad – very expensive to run.
We offer many more services including hydronic radiator and underfloor heating systems with multiple heating sources. These suit new highly insulated homes perfectly. A slow even heat, popular in European countries, with an efficient heat source makes this choice the lowest running cost of all home heating methods. All these quality systems cater for different budgets.
Consultations and calculations are essential as each system varies between lower install cost but higher running cost, or alternatively higher price install but lower running cost, made possible by top quality systems.
All these systems require maintenance and this is an area in which we have specialised training.
Underfloor heating or hydronic heating is basically heated water being pumped around various pipework circuits within the home’s foundation. The temperature is usually not set higher or circulated beyond 40 degrees. There is a thermostat that keeps control of the temperature and boiler control, and in a good system there is also zone control with multiple thermostats controlling each room independently.
The efficiency of the system is bound by two factors:
- First is the heat source and the cost of the fuel. It is possible to use water heated by Solid Fuel Boiler, HPHW or Gas boiler. As cost-effective means all of these systems have good efficient brands and models or poor ones; often it comes down to convenience (gas Or HPHW) or availability of free or very low-cost fuel but takes effort (Solid fuel Boiler).
- Second is insulation; trapping heat inside the building envelope. This starts at the foundation level. While it is possible to install an efficient system without perimeter insulation, the ultimate lowest cost efficient running system will have perimeter insulation around the footing line to stop sideways heat loss and under the concrete and poly will be another insulation layer so that heat does not migrate through the ground. The new home walls and windows are now very well insulated so this is not such a problem above ground level.
