Parkray & central heating.

[feebee102]

Hi can anyone help my sister.
She has recently moved to a bungalow in the countryside that has a Parkray fire with a back boiler that is supposed to provide her central heating.
All new radiators where fitted prior to her moving in.
She lights a fire and it doesn't take long before her water is piping hot but her radiators only get luke warm.
The chimney has been cleaned in the last two weeks.
She has tried using both coal and wood, but they give the same results.
She can cope at the moment with the milder weather but she needs to get it sorted before winter again.

Many thanks Fiona

Hard to say without knowing how the system has been installed. I can say though, that I guess it's a "thermo-syphonic" type of installation. (ie, relies on natural rising motion of hot water.) ........ will work a treat for hot water, but for rads, pipework has to be set up very precisely regarding pipe gradients for it to work at all. (In simple terms - the slope on the pipe runs.)
Modern pumped systems have no trouble pumping all around a system.
I assume there is no pump?

While I worked at the pit,almost every house in the village had Parkray back boilers for domestic and central heating supplies and nobody had any complaints,but as The Builder says they all had central heating pumps
