Boiler help!!

[lemzip]

Hi

we moved around 6 months ago a a different property. It has a Baxi boiler from the dark ages thats noisy and looks ancient and a grasslin towerchron qe2 panel. We also have a hot water tank that seems to be gas only and no connection to the electric.

The problem besides the cold in the upstairs (can be 5-8 degree difference with it being cold upstairs) is when setting the heating to come on the hot water come on no matter what.

In my previous properties we could use the timer to do them separately and it worked. This panel has the options but no matter what we set the heating to the hot water comes on for the same time even if not programmed. If we set the hot water only...no heating comes on?

Is this normal? The tank is set to 65 degree's but with upstairs being a fridge, its always kicking in even when the rooms have reached temp. Can anyone also please explain how the numbers on the actual boilder affect the heating? I can turn it down to 2 etc the heating kicks off but obviously if the actual thermostat is not at temperature how can this affect this?

We have just recently had the landlord put in an extra 170mm insulation ontop of 80mm previous but it does not seem to have made a difference to upstairs. Downstairs is lush!

thanks

Where is your thermostat located ? and do you have TRV's on any of the radiators ?

When the room where the thermostat is reaches the required temp the heating will turn off even if the other rooms aren't at the correct temp.

Its quite usual to have the thermostat in the hallway and TRV's on the radiators in the living room and bedrooms to control the heat in those rooms.

Hi

Only 1 tvr, the radiator by the front door into the the property, its sort of a mix and match of whats about here...some radiators have been replaced with newer double fin ones when it looks like rooms have been refurbished but others are old and rusted on the outside.

The thermostat is right at the front door and that area is the coldest part of the house so it really struggles to get to temp, think it turns off once in 3 hours testing if i set to 22 degree on the thermostat for a test.

The radiator is tiny for the area so never heats the downstairs door area, stairs and landing, its way to big for the size of radiator.

The door is pvc and has no air leaks/drafts etc...it just seems really cold there...maybe a curtain will help but think they look meh.

Any idea about the boilder and the heating/water on issue?

If it's an old system, then it's probably piped up in a gravity hot water and pumped heating fashion. Which means no matter what controls you have fitted the plumbing system will only do water on its own (and even then some rads heating up) or water and heating together. The system would need converting to a fully pumped system, plumbing, wiring and controls.
