Hi . I have a megaflo water tank and i want to ask the following.i noticed that after 2 or 3 showers i have cold water. Whats the point to have the water tank i dont understand. I thought that having gas i would always have hot water and now i rely on a tank? how is it possible to switch it off when i have cold water? is there any valve in order to switch it off sometimes?
Dimitrios... sounds like, your HWC is not big enough for your hot water demand from your property. The hot water in a cylinder will take a little time to heat up. A combination boiler outputs hot water near enough instantaneously. I recommend calling your local plumber for a diagnostics and then take it from there!
I hope this helps!
