I am looking at upgrading my bathroom, at the moment there is a combi boiler although a small unit and a water tank in the bathroom.

I am looking at removing the water tank and getting a bigger boiler what are the pitfalls of doing this or am i best keeping the water tank and moving it into loft ? apologies if this is a daft question no nails glue is about the extent of my building knowledge!

Im no heating engineer but I thought the Hot Water Tank had to be on the second floor or at least below the loft due to gravity working the water around the system?

Im not a fan of Combi boilers after the last one I had struggled to fill a bath, it was probably a bad boiler.

Our water tank is on the ground floor. I presume there is a pump somewhere, otherwise I have no idea how it works!

Combination boiler plumbed up with a cylinder isn't the norm.
If your incoming mains is up to it, size the boiler to match and rip the cylinder and tank out!?

You quite often get the stored water cistern basically sat on to of the hot water cylinder taking up a whole airing cupboard space. The flows naff but due to no loft, it's a common spot.

In regards to the Surveyors, could yours be an unvented cylinder. Hot and cold taps are both equal pressure? Maybe why you haven't heard a pump sounding.

Would make sense I guess. What it really is, is bloody unreliable.

It's limited to the boiler really - but as when that stops working so does our hot water it's all lumped in as an old system... Latest trick was that it does not switch off even when the timer is off and there should be no demand.

No immersion backup?
