central heating help needed please

[markeymark]

I have moved to a new flat. It has a baxi bermuda gas fire in the living room, with thermostat knob below fire. In my cupboard next to fire is a Randall 103 timer

Can anyone tell me if there is a leaflet to explain how these work?

I can use the fire, and some of the radiators heat up no problem, but i have 2 radiators which dont heat up, i have tried to bleed but only clear water comes out!!

Also my water is not very hot, any ideas, the property has been empty for about 6 months or more

all help apreciated

 

[kevplumb]

instructions here

and boiler here

as for the rads try turning the hot ones off and make sure both valves are open on the cold ones

 

[markeymark]

thnx for that m8, is it easy if i wanted to take out the gas fire and block it off, i do not really need it for the size of the room

could i get seperate controls for my heating then?

dunno if this makes sense, just i dont really have a clue about this stuff

 

[kevplumb]

if you remove the gas fire you cant use the boiler


not really if it is a gravity system

does the pump run when you only have hot water switched on ??

 

[markeymark]

it seems i can only have the hot water on whilst the heating is on, have just bought the flat and trying to do it up so havent really had time to have a proper look at it

how would i just get hot water on and no heating?

sorry again if i sound dumb

 

[kevplumb]

read the instructions in the link

ok m8 not got round to looking at it yet

thanx again

would it cost a lot to change to a combi or a diff boiler?, just think that the fire is quite unsightly

 

[ChrisR]

SOunds like it's a sytem where the HW heats by gravity circulation whenever the boiler's on, and the timer would bring the pump on to heat the radiators.
If there's no thermostat on the HW cylinder, the water temp will be controlled by the boiler's thermostat.

Combi replacement- aboout £1600 to 2400 in SE, see what Kev says - -he lives north of Watford.

 

[markeymark]

where is the HW cylinder?

 

[kevplumb]

look for one of these

might not be blue though

 

[markeymark]

ok m8, will go up into loft and have a look

thanks for your help

last question (for now0

if the fire cant be removed could it be replaced with a newer fire?

 

[kevplumb]

depends on the exact model of the boiler
there is a number on it 401, 552,45/3, 57/3, 45/4, 57/4, 51/5

renewal fire fronts are expensive tho

 

[ChrisR]

Just noticed you said Randall 103. That's a single channel timer. Unless there's another switch somewhere you would have to have CH and HW on together. If you used a 102 or something more modern (60's technology instead of 50's....) you should be able to have HW by itself, timed separately. You'd still only get CH when the HW is on.

 

[kevplumb]

missed that

ok np guys

thanx for all your help so far
