Should I repair or replace my boiler?

Boiler servicing

Boiler servicing FAQs — Wokingham

Why annual servicing matters more in Wokingham than in most of England — and what Thermotec’s service actually includes.

Boiler installation

New boiler installation FAQs — Wokingham

Common questions about choosing and fitting a new boiler in a Wokingham home.

How do I know if I need a new boiler?
The main signs are age over 12–15 years, two or more repairs in a year, and rising gas bills from falling efficiency. Stuart gives a free honest assessment before any quote. New boiler page →
What types of boiler do you install and which is right for me?
Combi, system and heat-only boilers — the right choice depends on your property size and hot water demand. Stuart is G3 qualified for unvented cylinder work most engineers can't do. Combi vs system guide →

Hard water & RG40

Hard water FAQs — Wokingham & Berkshire

Wokingham’s very hard water is one of the most significant factors affecting boilers, showers and plumbing across RG40. Understanding it helps prevent repeat faults.

⚠
Wokingham hard water: 330–380 mg/L CaCO₃
Wokingham sits on a chalk aquifer. The domestic water supply across RG40, RG41 and surrounding postcodes typically measures 330–380 mg/L calcium carbonate — classified as very hard and among the highest in England. For context, the UK average is around 200 mg/L. This means limescale accumulates on boiler components, shower elements, fill valves and pipework significantly faster than most UK homeowners experience.
How does hard water affect my boiler in Wokingham?
It scales up the heat exchanger, wears the expansion vessel and pump, and can clog the condensate system — causing kettling, pressure loss and premature failure. A magnetic filter and annual servicing are the main defences. Magnetic filters →
What is the best water softener for Wokingham homes?
Thermotec installs Kinetico water softeners, which genuinely remove calcium from the water, and Aquabion conditioners, which prevent limescale without salt. Kinetico → · Aquabion →
Should I get a magnetic filter for my boiler in Wokingham?
Yes — Stuart recommends one on every Wokingham installation and service where one isn't already fitted, and Vaillant/Worcester Bosch require one for extended warranties. Magnetic filters page →
Landlords & CP12

Landlord & CP12 FAQs — Wokingham

Gas safety compliance for landlords across Wokingham, Earley, Woodley, Winnersh and the wider RG40 area. CP12 from £75. Tenant liaison available.

What is a CP12 gas safety certificate and do I need one?
A CP12 is the legally required annual gas safety record for rented properties with gas appliances. Thermotec provides them from £75 with digital certificates issued the same day. CP12 page →
Can you liaise with my tenants directly?
Yes — standard on all landlord bookings. Give Stuart the tenant's number and he'll arrange access directly; certificates are emailed to you the same day.
Do you offer combined CP12 and boiler service?
Yes — the CP12 + annual boiler service combination is £150 (vs £75 + £96 separately). One visit, full Gas Safe inspection, full boiler service and both digital certificates issued on the same day. This is the most popular landlord option across Wokingham, Earley and Woodley — it completes legal compliance and annual servicing in a single appointment, reducing tenant disruption and total cost.
Heating systems

Heating system FAQs — radiators, UFH & smart controls

Questions about the full heating system — radiators, TRVs, powerflush, underfloor heating and smart thermostats across Wokingham and RG40.

Why are my radiators cold at the bottom?
Usually magnetite sludge settled at the base, blocking circulation. If several radiators are affected, a powerflush is typically the fix. Radiator services →
What is a powerflush and do I need one?
A powerflush clears sludge and debris from your heating system to fix cold spots and restore efficiency. Signs you need one: cold radiator bottoms, slow warm-up, kettling, or frequent pressure loss. From £550. Powerflush page →
Can I control my heating from my phone?
Yes — Stuart installs Hive, Nest and tado° smart thermostats and is the only Hive-trained engineer in Wokingham. Most homes save 10–16% on gas bills. From £300. Smart controls page →
Do you repair underfloor heating?
Yes — both electric and wet underfloor systems, including the boiler connections on wet systems. From £96 diagnostic. UFH repair page →
What is a G3 qualified engineer and why does it matter?
