Thanks for that.
What size unvented cylinder would you recommend for my house, 5 bed
2 bathrooms ? & and what size should the incoming water main be ?
Hi , 210 litre for a cylinder heated by the boiler , 250 litres if heated by immersion heater . The incoming main really should be at least 25 mm ,but the minimum flow rate needed is 20 litres a minute and 1.5 bar pressure. If putting vin a new main is practically impossible , a mains booster set can be fitted , ie in a basement which consists of a tank and pump set.
A mains pipe can be miles moled in as well which is a tunnel under process which can accurately tunnel a mains pipe from the road to a certain part of the house ( just search mains moling)
Does the 25mm incoming main have to be all the way to the boiler or can it be reduced in the house ?
