central heating insulation

[siqveland]

I've recently had a new CH system installed with plastic pipes... There is crawlspace under my house and I'm wondering if it is worthwhile installing pipe insulation???

Is the clip on foam piping ok?? anything better that I can use??

Thanks

If the pipes are in effect external and could be affected by the cold, then yes they should have been insulated. It will also help with energy efficiency.

use at least 13mm wall insulation.

thanks for your reply

Water regs stipulate 25mm insulation for 15mm pipe, which is much dearer than the pipe. Worth it though. My system has 9mm insulation and I lose 10% of the boiler's energy heating the rads, through the insulation.
It's a job which in commercial and good quality bigger domestic situations is done by a specialist. Doing all the fiddly bits takes time and the right methods/materials.

i may be wrong but i fail to see how you lose 10% throught pipes. i mean i bet the pipes have less surface area than all your rads, and your pipe do have 9mm of insulation. im not a plumber tho so may be wrong?

I'm looking at developing a product to insulate a domestic central heating pump. It would be easy to fit over the pump and could be removed to gain access.

Currently products are provided to insulate hot water pipes and the hot water tank in a domestic central heating system. It is estimated that pipe insulation can save around £15 a year and hot water tank jackets around £40 per year. But there is no product for the pump.

Early indications show that the product would cost approx £7 and would save approx the same valve per year in energy bills. Therefore the pay back for the product would be 1 year.

Any thoughts or feedback would be appreciated

Thanks

My view is that the makers would not like the motor head being covered.

Solar pumps already have insulation.

At least half of the heat lost from a pump adds to house heating.

The electrics would not be covered, similar to following Grunfos product:

The material would be fire resistant, not polystyrene
