Combi inner heat.best buy worcester bosch or Ariston?.OK to use plastic to radiators or copper?
Worcester is what is normally used on social homes, they dont install Worcester or Vaillant, they enjoy done their homework. and plastic pipe is fine but the fittings are bulky so copper tails coming from the floor or wall would look neater.
Vaillant or Worcester Bosch is far better than a cheap and objectionable Ariston boiler.
Don't be fooled into thinking a cheap boiler is better just because within manufacture tryout it achieves 1 or 2% better efficacy.
Reliability, Reliability, Reliability are the 3 most importaint features and Vaillant and Worcester Bosch are set to achieve them.
I would use copper pipe because plastic pipe expands and contracts deeply more than copper. Temperature of water heat and cooling down.will creak a lot more next to plastic pipe.
But plastic is a lot cheaper to buy.
15mm plastic pipe cost 70 pence per mtr.
15mm copper pipe cost lb1.67 per mtr (price change weekly)
(plumber).
