Delivery systems
Embedded in concrete
Pex tubing embedded in a concrete slab provides long lasting radiant heat. A large thermal mass is created so this is optimal for keeping buildings at a constant temperature.
Under floor heating Transfer plates
Aluminium plates attached to the bottom of the sub-floor are used to transfer heat to the living space above.
In joist bay Ultra-Fin
Aluminium ULTRA-FIN plates are suspended in the upper two thirds of the joist bay and transfer heat to living space above. This option has the advantage of covering more square footage with less tubing.
Radiators
Very traditional in hydronic systems radiators mounted to the wall under windows provide heat to the room. Can be installed with thermostatic valves to regulate the temperature at every radiator.
Baseboards
Like radiators baseboard heaters are mounted to the wall preferably under windows at the floor level.
Heating sources
Gas boilers
There are generally two types of boilers, condensing and non-condensing. Most modern boilers are condensing boilers. Non-condensing boilers are mechanically simpler but much less efficient. We work with all types of boilers.
Electric Air to Water Heat Pump
As the world moves away from fossil fuels electricity is the only option. Air to water heat pumps use a compressor to move heat from the air to the water. They are very efficient at moderate temperatures. We have replaced many traditional water heaters with electric heat pump units. We expect these to become the norm especially in Berkeley where they have banned new natural gas hookups.
