Hi there ! All the best wishes for 2024 ! I am hoping someone can help me ? I have been reading about the Honeywell MOMO Divertor valve. ( Ports A, B and AB ). I understand the valve only moves when mains power is applied - there is no spring inside this valve. There are 3 wires going to...

Ahh Flameport I understand now. So the E7 meter gives readings for DHW and Electrical Heating Panels, while the other single phase meter is for all the other electrical energy usage. How do you read and report the meter readings to the supplier ? Cheers

Many thanks - was wondering why there are 2 meters that provide a total of 3 meter reading ? Can any one help ?

Good Morning All I am hoping that someone can help me ? A friend of mine has move into a flat with I believe Economy 7 heating and hot water. The agent did not bother to explain how the system worked - chances are they did not know nor care ! My friend has the electric heaters switched off as...

Hi it is an unvented cylinder, however it has it's own 2 port NC valve installed as per the manufacturer's instructions.

Hi many thanks. I spoke to Resideo Honeywell Home heating controls and they said that they do not make a replacement head for the V4043B1257, which seems odd in that if it fails e.g. the spring gives up then it is a complete new valve ?? Odd ? I appreciate the motor inside can be easily...

Hi there ! I am planning to reconfigure my domestic central heating and hot water system. I need to convert a normally closed V4043H1056 2 port valve to a normally open V4032B1257 2 port valve. I appreciate that there will be wiring changes required as the normally closed 2 port valve does not...

Hi Many Thanks Out of curiosity is there a specific type of flux recommended for copper pipes ( to carry gas ) which can not / or are generally not flushed before being put into service ?

Good Morning I have a quick question for you all ! :) The other day I wiped off a very green stain from the copper gas pipe inside my house. The pipe runs to the boiler. It wiped off with a drop Brasso and there was no sign of a mark on the copper, where the green stain had been. I now...

Hi I was just thinking out loud and was wondering if it good practise to fit one to the incoming water main ?

Hi there ! I was wondering would it be a good idea to install a 22mm compression Y in line strainer on the cold water main ? I appreciate to be able to remove it for cleaning that an isolating valve would be required on either side. I was thinking that this might be considered to be good...

Morning Dilalio - many thanks - I was wondering are the 15mm type A drain valve capable of withstanding mains pressure ? in my case the static mains pressure is 7 Bar. This would be the case if it were fitted between the stop valve and the inlet to the PRV. I note on the PRV that that there is...

Good Evening I hope that you all had a good weekend. :) I am having the cold water pipe work altered in my house. I was wondering in order to be able to drain the cold water piping in the future I was thinking about having a type A drain valve fitted after the stop tap ? There is a PRV which...

Hi Everyone - many thanks for your replies - very much appreciated - I saw the recommendation to install a deaerator ( such as the Spirovent RV2 ) - as I understand it is a smart AAV - it is item now routinely fitted to sealed domestic CH systems ?
