I have almost finished the kitchen refurbishment in a property I am renovating and it will soon be time to have central heating installed including a new combi boiler in the kitchen.
I would be grateful for any ideas regarding pipe routing for the boiler before having a heating engineer down to look. See below for details.
Space has been left at the end of the wall unit run for the boiler and directly above that space I made a large void above a section of recently lowered ceiling ( needed to be lowered at that place for other reasons so presented itself as an ideal place for the boiler and piping ) to accommodate wet piping to the rest of the property. This gives near access to the notched joists that were used in the previous central heating system and subsequent access to the rest of the house for piping. Joist positions in the void would not obstruct piping rising up the wall on which the boiler will be mounted.
Unfortunately there is no viable option but to receive the gas supply for the boiler from below despite my dislike of pipes emerging from a kitchen worktop surface. The worktop in that place will remain removable until this has been completed.
Using the combi boiler in our house as an example, I see that pipes usually emerge from the bottom of the combi as that is where the unions are.
What I want to avoid on the renovation, if possible, is a bigish and intrusive pipe 'boxing in' situation below and to the right of the boiler where the wet pipes do an extended U turn and shift to the right ( to avoid the position where the boiler is actually mounted ) to make their way to the ceiling and the void.
My thoughts are these
1/. Is it permissible to mount the boiler on, say, 3" x 2" timbers, correctly spaced for the boiler mountings, fixed vertically to the wall to allow the wet pipes to pass behind the boiler and thus only needing a small U turn under the boiler avoiding any wide boxing in of pipes below and to the right of the boiler. ( Takes a breath ...... ). Obviously some diversion of pipes would be needed to avoid the flue. I could extend the 3 x 2 's to the ceiling to box in above the boiler - that would be OK and look much better than big boxing below.2/. Do all wall mounted boilers only have pipe terminations at the bottom of the boiler. Is there such a thing as 'pipe U turn kit' to address the problem.
The property is a renovation for rental so I'm going to be looking for a budgetish boiler - not necessarily the lowest price though as eventually it is for my daughter.
How have you overcome a similar problem? Just want ideas to offer to the heating engineer.
