Central Heating Pump

[eddiescully]

Hi my central heating pump is getting really hot when central heating on is this normal, it is working fine should i be worryed tho? its on the flow pipe beside the boiler maybe that is why its getting so hot or is it on its last legs because it is very old. What ye think guys?

When you think the water coming out the boiler could be something around 80C it would get hot.

If everything is working ok I wouldn't worry about it.

Again if it's getting on a bit, buy a spare, and keep it for when /if you need it.

The pump is cooled by the pumped water!

The body is uaually about 10 degrees above the water temperature.

If its excessively hot then thats a sign that its stalled and not pumping.

Read the FAQs about pump valves as these need to work to change a pump easily without draining the whole system.
