A Genuinely Local County Firm
Boilers Fitted Right Across County Durham
Connected Gas & Heating installs new boilers across County Durham from Office 22, The Old Brewery Business Centre, Castle Eden, TS27 4SU. Our position close to the A19 and with access toward the A1(M) makes Castle Eden a practical base for county-wide installation work.
We are a family-run business established in 1999, with more than 3,000 customers looked after and over 150 boiler installations completed each year. In addition, every survey considers the property, heating circuit, number of bathrooms, available space and future plans before a fixed quotation is prepared.
A County of Different Homes
From the Coast to the Former Pit Villages
County Durham includes historic city homes, East Durham settlements, former colliery communities, post-war estates, modern developments and older rural properties. New boiler design must reflect that variety.
East Durham Coast
Properties toward the East Durham coast can include older terraces, cottages and newer housing. As a result, external flues and condensate routes need sensible positioning.
Peterlee and Easington
Former pit-village and new-town housing often includes modern boilers connected to older radiators and pipework. Therefore, system cleaning matters before replacement.
Horden, Blackhall and Wingate
Mining-era terraces and post-war housing can contain heating systems altered several times. Consequently, a proper survey and full system assessment are essential.
Shotton and Rural Settlements
Homes outside the larger towns can have longer pipe runs and more varied layouts. As a result, straightforward like-for-like replacement is less common.
Stone-Built Rural Homes
Older stone properties can lose heat differently from modern homes. Therefore, correct boiler sizing and radiator assessment prevent underheating or unnecessary oversizing.
- Full system cleaning. For example, many older ex-colliery and rural heating systems benefit from a proper power flush before the new boiler is commissioned.
- Modern heating controls. Updated thermostats and controls help a new boiler respond more efficiently to the way the household uses each room.
- Soft county water. Most of County Durham receives soft water, which is generally kind to boilers and reduces heavy limescale concerns.
Advice Before Installation
Choosing the Right Boiler for Your Home
The right boiler depends on the property and household, not just the brand name. We compare combi, system and regular boiler arrangements before recommending the most practical installation.
Combi Boilers
A combi provides heating and hot water without a separate cylinder. For example, it can suit terraces, flats and family homes with suitable mains pressure and straightforward hot-water demand.
System Boilers
A system boiler works with a hot-water cylinder. Similarly, it can suit larger County Durham homes or households using more than one bathroom at the same time.
Regular Boilers
Meanwhile, a regular or heat-only boiler may remain sensible where a traditional cylinder and existing heating arrangement are in sound condition.
Correct Output
We size the appliance to the home's heat loss, radiator circuit and hot-water needs. However, a larger boiler is not automatically the better choice.
Future Household Plans
Similarly, extensions, extra bathrooms and changes in occupancy can affect the best boiler and hot-water arrangement for the property.
Efficiency and Controls
Finally, modern controls, correct balancing and a clean system help the new boiler operate efficiently after installation.

Fixed Prices and Flexible Payments
Every County Durham boiler installation is quoted at a fixed price before work begins. The survey identifies the appliance, controls, system cleaning and installation work required, so the scope is clear.
The fixed quotation reflects the agreed boiler, flue arrangement, controls, system preparation and any cylinder changes identified during the survey.
In addition, flexible payment options are available for suitable installations. The old boiler is removed and disposed of as part of the agreed installation work.
