Here are some of the answers to the most commonly asked questions, we hope this information will be useful to you and if you still need more guidance or help, please contact us using the links below

Should I repair or replace my old boiler?

Replace. A repair can sometimes be as expensive as a brand new boiler. And you could easily have more problems with a repaired boiler further down the line.

A boiler replacement is usually more efficient and more reliable.

Your new boiler will be covered by warranty too – so if it breaks, the manufacturer will repair it with no extra charge.

We can provide a brand new A-rated boiler from £1,795, or from £11.61 a month, including VAT and Gas Safe installation.

How much does a new boiler cost?

The costs for:

  • a brand new A-rated boiler
  • a brand new flue
  • all the right fixtures, fittings and safety attachments
  • installation from a Gas Safe Registered engineer
  • would traditionally set you back between £2,500 and £4,000.

Heat Nest can offer you exactly the same A-rated boiler, flue, attachments and Gas Safe registered installation from £1,795, or from £11.61 a month, including VAT.

Are Heat Nest installers trained and Gas Safe registered?

Yes. All of our installers are professional, experienced central heating engineers with Gas Safe certification. They all have additional accreditations for brands meaning you will also get additional warranty years applied depending on brand and installation type.

Will I get boiler cover from Heat Nest?

Not from Heat Nest, but you will as part of your manufacturer’s guarantee. Every new Heat Nest boiler comes with a manufacturer’s guarantee of up to 10 years.

You don’t need to do anything to activate your guarantee – we’ll register your boiler with the manufacturer as part of our installation service.

Our manufacturer guarantees are:

Worcester Bosch – up to 10 years
Ideal – 7 years
Baxi – 7 years
Vaillant – 5 years
Heatline – 2 years

For covering your wider heating system, you can take out one of our home cover plans, which are available after you purchase your boiler.

Will boiler installation make a mess?

If you are doing a direct swap and not moving the position of the original boiler and or converting an existing boiler. There will be no mess, our engineers are provided custom protection covers to ensure surfaces are protected.  If a more involved installation is required, any mess created from lifting boards or making holes in plasterboard will always be cleaned and tidied up.

Do I need to do anything before my boiler installer arrives?

Yes.

Before your installer arrives, clear away any clutter around the boiler – especially valuables and things that break easily – and make sure the boiler is easy to access.

Unless you are told differently by us, the boiler will normally be delivered between 7.30am and 9.30am on the morning of the boiler installation.

What is a Combi boiler?

Combi boilers, or Combination boilers, are the most popular type of boiler in the UK. They’re used by 74% of households.

They’re named ‘Combination’ because they combine a high-efficiency water heater and a central heating boiler all in one package.

Combi boilers are efficient and cost less in heating bills.

That’s because:

They only heat water when you need it, rather than storing hot water up
They’re small and compact, as they don’t use an external hot water tank

What are Thermostatic radiator valves?

Thermostatic Radiator Valves – or TRVs – are controls for your radiators. They regulate how much hot water flows into the radiator so you can adjust its temperature.

TRVs also let you turn some radiators off (for example, in a room you’re not using) without turning off the heating.

Why do I need TRVs?
The Government recommends that every household has Thermostatic Radiator Valves because they:

save you money on heating bills
use less energy
are better for the environment
but they are not mandatory.

What’s the cost?
Each valve costs £35 and you can add these to your order when you checkout.

What is a flue?

A flue is a pipe, like a chimney, that carries waste from the boiler outside. You can see your flue exit (the part of the flue that comes out of your house) on the wall or roof of your home.

Flues can either be square or round in shape.

If the flue is less than two metres off the ground, or underneath a carport or shelter, it’ll be covered by a guard. This looks like a piece of wire mesh covering the end of the flu.

When you buy a boiler from BOXT, we’ll also supply and fit a brand new flue for you, along with all the safety attachments you need.

Will Heat Nest flush my radiators and heating system?

Yes. As part of the work your engineer will carry out a MagnaCleanse flush on your whole system using a specially formulated cleaner manufactured by Adey. The MagnaCleanse system has been developed by Adey and uses powerful magnets to extract rust debis from your system.

Once the flush is complete and your system is refilled with fresh water, the engineer will add Adey MC1+ system protector. Adey MC1+ is formulated to protect against both system corrosion and limescale deposition.

Will Heat Nest do a PowerFlush?

No. After years of experience, we’ve found that using a Powerflush machine on an older system simply causes more problems.

Instead, we carry out a Chemical Flush – which is a highly effective way to keep your system protected, approved by our manufacturer partners.

What is a filter?

A magnetic filter, which we’ll provide and install with most boilers. It’s fitted to the boiler on the return flow. This catches any debris from your system and stops it getting into your new boiler.
