new programmer question

Have just moved in....... I have an old danfoss hot water and heating programmer. manual clock and off, on or timed settings on both circuits. I want to get a new programmer fitted with a digital clock etc that can have different settings for weekends etc. Also the wiring to the 2 port valves on water and heating needs re-doing - i think. basically a new junction box and rewire this.

I am no electrician myself so will not touch it.... but......

Do I call in a normal electrician to do this or a corgi heating engineer?

thanks.

I have yet to find an electrician who truly understands heating wiring, get a good corgi in.

Thanks.
