I have a powermax 155x boiler (without a guage). We have a problem at the moment with the hot water supply. We can get hot water with taps open slightly, but as soon as you ask for more water, IE open two hot taps or open up a tap fully, the pump cuts off, which results in no hot water. If you wait a min or so, then you can get hot water again (only low pressure). Any ideas?
Hi I am really sorry we havn't been able to answer your question, this is a very strange scenario and i personally feel that it would be in your interest to get an engineer to actually be hands on. Obvously if you wish you can wait longer to see if anybody online can help, or just answer has a cancel anytime policy if you would like to contact the moderators they will do this for you. my apologies once again and good luck with your problem. Best regards Brian
