About this blog

This is a short blog about the thinking process, installation and results of a combined ASHP, MVHR, PV, EV charging and Water heating coil system being installed in a bungalow with good insulation and air tightness.

 

Be warned! The theory, installation and results assumed may not be right and I will only be sure when the job is completed.

 

Should you have any questions about this PM me and I will try to include an answer in the blog.

 

Good luck with your home
