Vaillant ecoFIT 415 heat only boiler. Connecting the pump and boiler?

[raidac]

Vaillant ecoFIT 415 open vent heat only boiler. For wiring the boiler and pump, should I use the 3-way wire switch" solution OR a "remote switching" solution? The pump and copper tank are situated about 25ft from the boiler. I've been told that the 3-way cable solution doesn't work well with this boiler. Thanks

I don't know what the 3 way wire switch solution is.
Is this not an 'S' or 'Y' plan?

It's Y plan and a I'm changing to S plan. The guy installing it wants to use a Grundfos pump. Another person said
Brittherm pumps are better. Do you have an opinion on this?

Brittherm Ltd is an importer operating out of a trading estate in Wembley it was incorporated in 2018 and had 4 employees during 2021. It's what's known as a 'micro-entity' by Companies House.

Grundfos is a leading engineering company and manufacturer. It's been around for ca 75 years and employs ca 20,000 people.

I imagine Brittherm pumps will be cheaper but in my experience you get what you pay for.

I have used Grundfos for many a decade now and find them to be good quality and have good after sales service.

If you're changing to 'Y' from 'S' you will probably need a bypass. Your Plumber probably knows this.

Thanks Chuck. It sounds like a person was trying to promote their friend's business. I'll stick with Grundfos
