SOURCE: my thermostatic concealed shower valve only gives

Hi,

If the hot and cold are fitted the wrong way round then the thermostat on the shower unit cannot operate properly!

Most thermostatic mixer showers have a 'bi-metallic' thermostat, if you supply the hot to the cold and vice versa IT WILL NOT WORK.

It is like wearing the left shoe on the right foot and the right on the left! It doesn't work.

Re-install the hot and cold to the correct supply, and this will sort it.

I hope this helps.

Ravenheat 80/20 boiler. the boiler looses water pressure but only when working in central heating mode. Boiler holds pressure indefinitely if central heating is not used,hot water can be drawn without a...


Hi, your boilers pressure should be holding 1.5 bar with the relief set about 3. If the pressure is below this the flow switch will cause the boiler to stop as theirs not enough pressure to operate. Another thing, does your boiler have an auto fill system or do you need to plug a hose in to fill it? If its an auto fill system and you lose pressure you could have a leak.

Boiler recycling when in DHC mode and water alternates hot then cold, back to hot every few minutes. Could it be pressure / flow rate.


First check pressure over 1 bar ok then-
1. check flow - is it adequate - a little less than the cold tap ok then -
2. does the boiler initially fire up on low hot flow but alternate as u say
If answers are 1. no but 2. yes then check for a furred up secondary heat exchanger
if 1. yes but 2. no [that is the water not the heating] goes hot / cold and if the boiler goes out when the water goes to cold then it's the diverter valve, either to replace or if it is one which has a internal diaphragm-replace that

Non i;n working boiler


Did you put automatic vent plugs on this boiler?This help stop from having air locks.I would try bleeding the high pipe to see if any air come out.The other thing I would check is the valve that out for the pump to pump water around.
