Sytem/Convetional Boiler to Combo Boiler

Waterlily24

We have a Worcester combi boiler in a four bedroom, 3 bathroom house and wouldn't change it. Ok it takes a little while for the hot water to come through but not that long and it's not a problem for us. I love the fact that there is hot water all the time. Ours is an oil fired boiler. Ours is about ten years old too.

How about having all the existing hot water on a pump, not just the shower? Must be cheaper than changing the boiler.

Just build a platform at the apex of the loft, relocate cold tank there, and do away with the pump. Don't forget to insulate it.

It's not the same as pumped! Great showers but noisy.

Nah. I have a combi boiler, and would love to go back to conventional. I have to wash my hands in cold water. GF turns on hot tap when she sits down to pee, as it takes that long for hot to come through.


If you have a tank in the loft, you can get it raised to give a faster shower, or install a pump to give the same effect.

Mine is in about a year and I love it.
The dishwasher and washing machine are cold fill.
I shower every morning under an electric shower.
And I live alone.

Thanks every one for the replies.

Can we install a booter pump that will increase the water pressure and solve the problem?

The first product boosts from a cold water header tank in the loft and the hot water cylinder to provide higher flow rates/pressure to the shower outlet.

The second product provides boosted mains cold water to all fittings and doesn't work with the cold water header tank - it would also normally be installed alongside a mains pressurised unvented hot water cylinder to provide boosted hot water as well.

Completely different products. However, if you're just looking to improve the flow rate to a single shower head then option 2 is an extremely expensive way to do it - you would only do this to improve pressure throughout the house, and you would have to get the right hot water cylinder as well to get balanced supplies.

I thought your Mrs didn't like the noise? That's why I suggested raising the cold water tank, and doing away with the pump.

Yes you are right she dont like the noise coming form the cupboard in the master bedroom.

Unfortunately I am planning to board whole loft and also plan to remove the tank from the loft.

Was searching Google to have an idea to increase the mains water pressure or alternatives so taht we can get good water presuure in the bath showers withour using that pump located in the cupboard next to the hot water tank.

We have a Mira pumped digital shower which boosts the shower pressure more than enough. They are easy to fit but quite expensive to buy.

The pump is built in to it ands sits in the loft above the shower cubicle. The noise from the pump is barely audible above the sound of the water.
