Question 1

Will a smart thermostat work with my older boiler?

Accepted Answer

Most smart thermostats are compatible with older boilers but need a compatibility check for wiring, pump controls and the programmer. We carry out a survey to confirm whether a wired thermostat, relay box or a wireless receiver is needed and advise on the best solution for safe integration.

Question 2

Can you install smart controls on a Vaillant boiler?

Accepted Answer

Yes — Border Heating Services Ltd are Vaillant accredited, so we regularly integrate Vaillant boilers with their recommended controls and third‑party smart thermostats. Accreditation ensures we follow manufacturer guidance and retain warranty conditions where applicable.

Question 3

How disruptive is the installation?

Accepted Answer

Most installs are straightforward and completed in a few hours with minimal disruption: mounting the thermostat, wiring or fitting a receiver and commissioning the system. Where radiator TRVs or extra wiring is needed, we'll explain the scope during the initial survey and schedule the work to suit your household.

Question 4

Will a smart thermostat reduce my heating bills?

Accepted Answer

Smart controls improve how and when your heating runs by removing wasted heating time and enabling zoning, which can improve efficiency. Actual savings depend on property insulation, household habits and thermostat settings, so we set practical schedules and advise on optimisation during handover.

Question 5

Do smart thermostats need a constant internet connection?

Accepted Answer

A stable Wi‑Fi connection is required for remote app control and cloud features; local heating schedules can still operate if the internet is temporarily unavailable. If Wi‑Fi is weak, we offer solutions such as relocating the router, using a wired receiver or configuring the system for reliable operation.
