Central Heating

[brifos]

We've just had a small extension built with one radiator - which just would not warm up. Then we found it would if we turned off the old one nearest to it. How can we get BOTH working together. PLEASE!

Several things to think about Bri ..........
Is the boiler big enough (probably is)
Is the boiler thermostat turned up high enough
Is the new rad connected in properly
Is the pipe bore (diameter) to the old rad big enough to give extra flow capacity to run the new rad
Is the pump speed set high enough

Most likely though............ rad balancing needed ......... i.e. reducing the flow to other rads to effectively give more flow to the new one.
