Gas central heating is the best way to heat your whole house.
The best and most efficient way to install the ducting is under the house to the various heat outlets, as heat naturally rises.
Raypak’s residential gas Pool and Spa heater range features:
The heating of a spa requires one of the powered forms of heating, that is, either gas, heat pump or element.
The spa may be heated by a dedicated heater OR by the pool heater, if the hydraulic design allows.
Where a single heater is installed, there will be a need to alter valve settings to circulate the water between the spa and heater only, with the pool isolated, while a fast temperature rise is achieved in the spa.
The valve changeover and resetting can be done manually or by automated switching/valves.
