Radiator issue

Bob..loblaw · 28-01-2014 6:26pm #1

Hi,

I'm working off a range that should be able to heat all the radiators I have. The problem is that a couple of radiators will get warm and then get cool again even though the fire is at the same level, whilst the other radiators wont heat up at all. I have bled them but that didn't change anything. I also use oil and the radiators get hot in no time. Could anyone suggest a reason for this?

Thanks.

Nobody has any ideas? Do you need more info on the problem? Any advice would be appreciated.

Is there a pump that only kicks in when you switch to oil?

Separate pumps. I can hear the one in the kitchen every now and again but shouldn't the water get hot and constantly circulate instead of this warm for 30 seconds then cold for a long time?

Ranges are notoriously inefficient, but it would depend on the make/model, age, system parameters/pipework, etc.

Do you get much hot water from the solid fuel side or limited?

Loads of hot water, it's a stanley range about 5 years old.

What temperature is the pipe stat set to & what location is at & is it on the flow or return pipe?

can you bleed the radiators

If they are heating with the oil side, it's not air.
Sounds like a poor location of the pipe stat to me, probably located on the return.

It's always set at between 60 and 70 degrees. Is there any trick to knowing if it's a flow or return pipe? I also just saw a myson control fixed to a different pipe than the pump. It is set to automatic, should I set it to manual? Is this what controls the circulation of the water?

That's a motorised valve & will be for the oil side.
Can you post a pic of the stat?

You need to balance the radiators for the range cooker and change to pipe stat to 40-50c (if stat is on the common return). The return should be the cooler pipe.

Here's the pic. Everytime I mess around with the stat I can hear the pump come on. I did this for a few minutes straight and the radiators seemed to stay on.

Ok. It's on the flow which is good. Set to 50-55C. Any lower will lower the hot water cylinder temperature to the set point when the fire dies down & it will use the cylinder as the boiler.

Ok I'll give it a go and let you know how it goes. Thanks for the input.
