LTHW BOILER SYSTEM PIPE CONNECTIONS :
ABOUT THE HEATING CIRCUIT :
A separate heat source is required, typically a fuel boiler or heat pump boiler.
The Heatstar simply transfers the heat provided by the boiler into the pool room air / pool water, when
necessary.
The heat produced by the boiler is taken to the Heatstar using a closed circuit of pipe work filled with water,
similar in principle to a standard central heating system.
The boiler heats up the water within the closed pipe circuit, which the boiler circulating pump then pumps
through the pipe work to the Heatstar.
The Heatstar transfers this heat from the closed pipe circuit, prior to the water being re-circulated back to the
boiler for the heating process to continue.
This type of circuit is known as an L.T.H.W. system (Low Temperature Hot Water).
BOILER TYPE :
The boiler required is a normal domestic / commercial type, identical to that which would often be used to
provide heat to standard radiators.
Ground source heat pump boilers, air source heat pump boilers or heat stores can all be applied for this
purpose.
The flow temperature provided from the boiler is critical to the heating ability of the system. If the flow
temperature is inadequate, then effective heating will not be possible during colder weather. To use a heat pump
boiler, the Heatstar unit would normally be especially configured during manufacture to compensate for the
comparatively low flow temperature available.
A specialised
‘swimming pool’ boiler cannot be used as these can usually only be used to heat the pool water
and not the pool room air.
High efficiency condensing fuel boilers can be used.
Pressurised system fuel boilers can be used as long as the pressure is not normally allowed to exceed 30 P.S.I.
On a fuel boiler, a balanced flue arrangement is preferable and necessary if the pool room air can enter the
boiler plant room.
Two smaller boilers can be used, in place of a single large boiler, if this offers any plant room space benefits.
BOILER SIZE :
The amount of heat which a boiler is capable of producing is described as the boiler out put capacity. This
should not be confused with the boiler input rating which is not the same.
This will normally be rated in BTU
’s (British Thermal Units) or kW. (3412.14 BTU’s = 1 kW ).
The required boiler heat output rating are detailed in the data contained within the
‘Installation Services’
document supplied with the product, further copy available on request.
Contact Heatstar if there is any doubt as to the correct out put rating.
