Hot water boiler
Hello. I was wondering if there is anyone who can help. We have recently had a new bathroom fitted with a walk in shower. We love the job they did. Unfortunately against my better judgement I let them fit a gas boiler for instant hot water even though they werent plumbers or gas fitters. The problem is the water keeps running hot and cold and this is very worrying as we will have our young grandchildren coming to stay with us and we are frightened that they could get burned. I have tried adjusting the water temperature and water pressure but to no avail. If anyone has a solution or can be of any assistance it would be greatly appreciated. Of course we would pay if any one could fix this.
