Tryin to Get Fire to Heat Radiators

sparklespark

Hello,
I moved into a house few years ago but never lit the fire. Lit the fire last week for the first time. It is heating the water fine. But I am wondering how to get the radiators. There is a pump in hotpress with plug. DAB 55/130 is the name and model of the pump. I have plugged this in at socket. But radiators not heating . Is there an on/ off swith on pump - do I need to turn any other wheels to turn this on. Any help or advise is much apreciated. Thanks

pump may have seized if not used for a while
try plugging it in and tap the metal part of the pump lightly with a hammer

Will try the hammer tap. The pipe going into pump is hot. The pipe coming out of pump has red wheel on it. What direction should this tap be in clock wise or other way. Thanks for help hope it works

meercat

just give it a series of small light taps
any direction should do

Hi can you help me with the red tap that is on the outlet of the pump should it be turned clockwise or anti clockwise

meercat

`not sure what it is
any chance of a pic

What...no it won't

If there is a valve with a red weel on top, turn it anti-clockwise to open, but be warned they are notorious to size...



The pump has a plug, does the wire go directly from the plug to the pump or are there other wires, they may go to a pipe-stat somewhere.. would look something like this, if there is try turning it down in temperature which will have it coming on sooner, I think ours is set to 50degrees..


If there is only a plug and wire into the pump, then plug it in and if the pump is running you should feel just a slight vibration...
A light tap might help.. dont beat it though as it may crack the housing :eek:..
Maybe check the fuse in the plug ?

If you can stick up a photo it would help

Sorry computer not playing with me this week so cant upload a pic. Pipe going into pump is hot enough. Pipe is directly below Water tank. Then pipe is connected to pump. Outlet pipe from pump has red wheel. My water tank is heatin fine with fire Have turned pump on while ago and no noise or movement of hot water to radiators. Sorry any advice.

meercat

sorry misread your post
i thought you wanted to know what direction to tap the pump with a hammer:mad:

Hi yes I have turned that red wheel on.. have it totally anti clockwise. Yes there is orange temp gauge like u say

Yes I have turned it anti clock wise the pump is not making any noise and you i have the same orange gauge. If u manage to sort this out i honestly will send u cheque.

On the side of pump there is a slight thing that you could move with a knive. It was at quarter past i have moved it anti clock wise to half

meercat

the orange gauge is a pipestat
it allows the pump to switch on automatically when there is hot water in the pipe and continue to run until the water cools

OK..
If you are sure there is no vibration from the pump then it's not coming on..

There are a number of possibilities...

1. No power to the pump, it's possible that the fuse to the pump is gone, replace the fuse in the plug and try again.

2. PipeStat. If you definitely have power to the pump then try turning the pipestat right down when the system is warm. If you listen carefully then you can hear the stat click as you turn over and back... If the pump doesnt come on then the pipestat isn't the priblem (95% sure) Make sure it's plugged in and switch on socket is on :rolleyes: (ive done this myself)

3. As stated previously the pump could be stuck/siezed.. You'll need a plumber

4. Pump could be dead... You'll need a plumber.

5. Is there any chance the pump is coming on?? There should be a silver screw in the face of the pump like this..

Carefully screw it out, if the pump is airlocked then this will release the trapped air and the pump would prime itself and work.. Try not to remove the screw, back it out until either water or air trickles out, dont back it any further.. if air comes wait until water comes and then tighten.. If water comes, again wait a few minutes and then tighten.. this airlock caught me out once and took me 2 hours to figure:rolleyes:

If you get through these and still no joy I'd recommend getting a plumber or someone more confident of troubleshooting the problem who would have meters to check voltages etc.. (no offence intended)

As above, but check in the attic to see if there is a small tank supplying water to this system, it is separate to your main water.

Yes the pipestat clicks when i turn it to certain degree

5. Is there any chance the pump is coming on?? There should be a silver screw in the face of the pump like this.. I opened this screw in centre of pump. Air or water did not come out. Maybe I should have opened it more. Should the pump be on or off when I open this screw?

Thanks for your help - Please see above answers. The pump does heat up when it is switched on but the heat does not transfer out to the outlet pipes.

Have you checked the Fuse Board. You may have an MCB breaker dedicated for the heating that is switched off completely for the Summer. I've seen that problem before.
If you are sure you have power then turn the stat until it clicks. Which means the rads are calling for heat and the pump should switch on. Don't be afraid to give the body of the pump a decent tap of a hammer., say holding the hammer from about 2 feet above the pump. then move the hammer around the pump body tapping from different points.

What happens is when the pump is left lying unused over the summer the water in the system accumulates gunge over time, this settles in the pump and acts like a glue.
Once you can get it freed it should be fine.
Failing all that a new pump is about 80 Euro.

Hello,

thank you all for your ideas. I finally got heat to the radiators.
I unscrewed the silver button in the middle of the pump.
Then I put a flat head screwdriver into this hole and moved it round - this ended up spinning the pump - air came out for few seconds and pump remained spinning round on its own. Radiators heated up in no time.
