Thinking about a heat pump in the North East? This guide explains how they work, if your home is suitable, rough costs, grants and what to expect from Wellington Wallace Renewables.

Heat pumps for North East homes, not just for show homes

If you live in the North East, you’ve probably heard a lot of noise about heat pumps, grants and targets.
What most people don’t get is a straight, engineering led explanation of whether a heat pump actually suits their house.

This guide is the “no fluff” version. What they are, when they work well, when they don’t, and what we look for before we’ll ever recommend one.

In a nutshell are heat pumps right for you?

• Heat pumps work very well in well-insulated homes with decent radiators or underfloor heating.
• Older or draughty houses can still work, but only if the heat loss and emitters are sorted first.
• A good design runs the system at low flow temperatures most of the time, that’s where the efficiency lives.
• Grants like the Boiler Upgrade Scheme can reduce the upfront cost, but you still need the right property and design.
• The installer matters more than the badge on the box, design and commissioning make or break it.
• If someone offers a quote without a proper survey and heat loss calculation, be cautious.

How a heat pump actually heats your home

Think of a heat pump as a reverse fridge:

• It collects low grade heat from outside air or the ground.
• A refrigerant circuit upgrades that heat using electricity.
• That heat is then passed into your heating water and hot water cylinder.

Key differences from a boiler:

• A boiler burns fuel and can run at very high flow temperatures (70–80°C).
• A heat pump moves heat and is most efficient at lower temperatures (typically 30–50°C).

That’s why emitter sizing (radiators/underfloor) and insulation are so important. The system is designed to run gently for longer, not blast on and off like an old gas boiler.

Is your North East home a good candidate?

When we visit homes across Newcastle, Northumberland, Durham and the Borders, we look at four big things:

1. Heat loss and insulation

• Wall type (solid stone, cavity, timber frame, etc.).
• Loft / roof insulation levels.
• Windows and doors.
• Any obvious draught paths.

If the fabric loses heat too quickly, you either need a larger, harder-working heat pump or some fabric upgrades first. We’d rather be honest about that than fit a system that struggles.

2. Emitters,  radiators and/or underfloor

We check:

• Radiator sizes and types.
• Flow temperatures required to keep rooms comfortable on a cold North East day.
• Whether underfloor heating is fitted correctly (spacing, controls, manifolds).

If every radiator is tiny, you’ll need higher flow temperatures, which kills efficiency. Sometimes we’ll recommend a handful of radiator upgrades rather than a bigger heat pump.

3. Existing heating and hot water layout

• Combi boiler vs system boiler with cylinder.
• Pipework routes, pump locations, and any existing zones.
• Cylinder location and size, or space to add one.

Heat pumps work best with a cylinder. If you’re moving from a combi, we’ll look at where a cylinder can sit and how that affects your airing cupboard or storage.

4. Electrical supply and outdoor space

We’ll check:

• Main incoming fuse rating.
• Board capacity and earthing.
• Space for the outdoor unit with decent airflow and minimal noise impact.

For rural and coastal North East sites, we also think about:

• Wind exposure and snow drifting.
• Salt air on the coast and how that affects siting and protection.

Air source vs ground source, a quick steer

Very simply:

• Air source heat pumps
  • Take heat from outside air.
  • Easier and cheaper to install.
  • Good for most typical homes where you have a sensible outdoor spot.
• Ground source heat pumps
  • Take heat from the ground via trenches or boreholes.
  • Higher upfront cost and more disruption.
  • Can be incredibly stable and efficient when designed properly.

We’ll only suggest ground source when:

• The property and land genuinely suit it.
• The budget and grant support stack up.
• It will deliver something meaningfully better than a well-designed air source system.

Rough cost picture and grants (without the sales pitch)

Costs vary with:

• Property size and heat loss.
• Level of necessary radiator / pipework upgrades.
• Whether we’re also integrating MVHR, controls or other renewables.

Grants like the Boiler Upgrade Scheme currently offer a fixed contribution towards eligible air source and ground source installs in England and Wales, paid via the installer. The exact amounts, eligibility and end date can change, so we always point clients to the latest official guidance on GOV.UK and Ofgem rather than promising a number that might move.

Our approach is simple:

• We estimate total project cost.
• We show the grant portion separately.
• You see what you actually pay, not just the headline grant figure.

Common mistakes we see with North East heat pump installs

In the field, we see the same problems over and over:

• No proper heat-loss calculation, system sized off floor area or guesswork.
• Radiators left unchanged, the system can only hit comfort by cranking the flow temperature.
• No thought about defrost and drainage, units sat in puddles that become ice rinks.
• Controls set up like a boiler,  on/off room stats and aggressive schedules that cause cycling.
• No clear handover, homeowner left with a thick manual and no idea what half the screens mean.

At Wellington Wallace Renewables, we won’t put our name on an install unless the basics are done properly. Your comfort and running costs depend on it.

DIY checks vs when to call an engineer

Things you can sensibly check yourself

• Energy bills and usage
  • Compare kWh usage to past months or years, look for big unexplained jumps.
• Outdoor unit airflow
  • Clear leaves, rubbish and snow away from the unit (without poking anything inside).
• Radiators and underfloor loops
  • Feel for obvious cold patches and turned off TRVs in key rooms.
• Controls and schedules
  • Check that schedules roughly match when you actually need heating and hot water.
  • Avoid constant manual overrides.

When to call an engineer

Get a qualified engineer involved if:

• Rooms never reach a comfortable temperature in cold weather.
• The system is noisy, short-cycling or constantly stopping and starting.
• You see error codes, warnings or backup heater messages.
• You suspect refrigerant issues (e.g. unusual icing or hissing).
• You’ve just moved into a home with a heat pump and have no paperwork or design info.

This is where Wellington Wallace Renewables is strongest: diagnosing whether the issue is design, setup, controls, or a genuine fault and then putting it right.
