What boiler
Ive just moved into 5 bedroom house with 2x bathrooms which are 1x bath + shower and a separate shower room. There are four people in the house 2x adults and 2x young children under 5 . The details are I get 2.7 bar and 30l/m at the outside taps with no other taps running, I also get 17-18l/m from a kitchen tap. I'm looking to replace my current set up with either a large combi Worcester 440 or 550 or use a unvented indirect cylinder. The water connection to the boiler will be straight from the main input before it goes to the remaining tap What would be best for now and long term, my concern is that the 550 can give 25l/m but what happens after the internal water storage is spent ?My cylinder concern is what happens after the water runs out and reheat time , is the cylinder being topped up as it is being used and is it being heated at the same time as long as the HW time is on ?im looking to install 210lt or larger , the existing is only 140lt . Another issue is due to space I may put either the combi or the cylinder in the loft and then feed down the hot to loft shower room and the bathroom on the 1st floor and where possible rerun the pipes in 22mm , wil there be a big drop in bar or pressure by moving it to the cylinde though I guess gets back some due to the drop from loft o 1st for bathroom?I was even thinking of a two comi approach, one for main bathroom and another for the loft shower , remaining HW and CH needs? Obviously dearer Your thoughts would be welcomed Thanks
