Advanced apology for bringing O/T to a Lotus7 forum!
I am NOT An expert so please attempt to understand my layman's language.
Circumstance:
House 1952. Gas central heating. I understand "gravity fed" . Recent remove old radiators and have new. Replaced working but noisy underfloor pump, existing pump which has been in 20 years.
Had a new wall thermostat and digital clock fitted about 6 months ago
Also had a new towel rail fitted to replace radiator - using existing pipe work
System all worked OK.
With the timer you had to have the hot water on to have central heating working. You could have hot water only on but not central heating only on.
Have had all radiators replaced for new ones, and a new C/H pump, system flushed and inhibitor added. that's all.
Here is the bizarre!
Today, with the hot water only to come on timer - the towel rail heated up and upstairs ONLY the pipes around the base of the radiators were warm!
Test carried out, did override on hot water to prove to myself what I'd just experienced.
Then I turned up the thermostat in the hall and all the upstairs rads came on, with the Towell rail and downstairs rads remained cold. ( bearing in mind the central heating according to the timer was off)
Contacted company, they will come back and take a look , but insisted they only replaced rads and a Pump , which is true . Trying to arm myself with some knowledge from the POBC , any thoughts as to what the issues are please?
Installer tells me Towell rail should come on with hot water, but when it was just a rad it did not!
In the cylinder cupboard there are an array of pipes! There are no electrically operated splitters or diverters. I THINK it is only a one pipe gravity fed system.
Please, sensible replies only
