New central heating - any advice?

[OddBoots]

Our boiler is old and noisy and in a room we want to start using as a bedroom so it needs replacing. The rest of the system is fine but I recall that new systems don't need to use a hot water tank and as that extra cupboard space could be useful that sounds like a good thing to me. The shower pump currently sits next to the hot water tank so that may well need to be moved (under the bath?)

We've got what we think would be enough savings to cover the cost but I need to work out timings in terms of time off work while it is done. Does anyone know if it's the kind of thing that can be done in a day or if it's more likely to be a few days or more?

Does anyone have any additional useful advice? I get very anxious having people I don't know in the house so I like to know what to expect.

Thanks in advance. :)

It doesn't take long. We got it done as a homer over 2 evenings. That was taking the water tank and the boiler out of the cupboards, putting the new one in the loft and we also got a radiator put into the kitchen as there wasn't one.

Depending what system you get you might not need a shower pump.

However if you are thinking of doing away with the cold water tank and the hit water cylinder it is vital that the installer tests the incoming water supply flow and pressure.

For a start fill a bucket at the kitchen cold tap or garden tap, time it, calculate how many litres per minute you get.

How many bathrooms and showers have you got, and how many people might turn on taps, washing machines, or flush WCs at any one time?

Thank you. :)

We are in a 3 storey house with a shower room on the ground floor (electric shower) and a bathroom with a shower over the bath on the top floor (the pumped one). The pressure on the ground floor is very good, in fact we have had to use isolators to reduce the pressure to avoid getting soaked at the sink but it obviously drops as we go up the house.

And the bucket?

Are the cold taps in the bathroom all fed from the cold tank, or are some from the mains?
