New Boiler (combi to replace gravity fed/cylinder)

kpk2000

As well as a new en-suite I have been getting quotes for a combi boiler to replace an older gravity-fed/cylinder system due to low water flow in shower & inefficient system boiler. Quote is for a 4 bed house with a bathroom (no shower & the bath is never used) and en-suite (shower used daily) and just 2 adults.

We appreciate the size of the house a combi and the implications for running hot water simultaneously but we are both combi veterans who like a good hot shower and never plan to wash up & shower at the same time! Water flow is 16 litres per minute so apparently quite good according to advice. It is replacing a 10 year old Potterton non-condensing boiler (one of the engineers quoting took a photo as he had never see a non-condensing type installed in a 10 year old house and was stunned by it!)

Best quote so far (of 4) is below and would appreciate some guidance on figure.

• Supply & install Worcester Bosch 38CDI Classic combi boiler and standard horizontal glue. (never had a
  
• Remove old boiler, cylinder and tanks in the loft.
  
• Install a Worcester Greenstar central heating system filter.
  
• Install the Worcester Wave thermostat.
  
• Connect a new gas run to the boiler (upgrading from 15mm currently and is about a 5m run - proposals are to run outside the house as saves pulling up chipboard flooring & gas meter/boiler on same side of house)
  
• Alter the pipework in the airing cupboard by bringing it forward to free up space for a larger shower tray in the future. (This is so we can install a bigger shower tray by knocking through into the airing cupboard a little later this year once the cylinder is removed. Better to get this done while doing this)

Do you intend in staying in this house forever?


I wouldn't dream of buying a 4 bed 2 bath house with a combi heating system. So if you plan on selling, it could potentially put sad people like me off.


In saying that, looks like the boiler costs around £1200 and £200 for the thermostat, so £2755 doesn't seem like too bad a price. Maybe a tad high.
