Full heating systems designed from scratch, calculated properly and installed by skilled engineers
DW Plumbing design and install complete heating systems for domestic properties across Cumbria, Lancashire and the Lake District. From heat loss calculations and system design through to radiators, cylinders, pipework, and controls, we deliver fully tailored central heating installations built around your property. Every system is designed in-house by our own engineers and installed personally from start to finish, with no subcontractors involved at any stage.


Central heating installation tailored to your property, ensuring maximum efficiency and longevity
A full heating system installation is not a one-size-fits-all job. Every property has different insulation levels, floor plans, occupancy patterns, and heating requirements, which is why we design every system from scratch based on a thorough assessment of your home. We carry out heat loss calculations, review your floor plans, assess insulation and EPC ratings, and calculate the BTU output required for every room before recommending a solution. Whether you are replacing an outdated system, upgrading to renewable heating, or starting from scratch in a new build, we will design and install a system that performs correctly and efficiently for years to come.
"Joe and Josh replaced our entire heating system including new pipework, radiators, and cylinder. They worked cleanly and efficiently, protected the floors throughout, and left the house tidier than when they arrived. The system has been faultless since installation. Outstanding work, would recommend."

Questions about full heating system installation answered
Common questions about full central heating system design, installation costs, timescales, and how we approach every project differently based on your property.
The cost of a full central heating installation depends on the size of your property, the complexity of the system required, the type of heat source being installed, and whether any structural work is needed for pipework routing. Rather than providing a rough figure that may not reflect your specific project, we carry out a thorough property assessment and provide a detailed, itemised quote before any work begins. Every system we design is tailored to your home and your budget, so get in touch and we will give you an accurate, honest price.
A full central heating system installation covers everything from system design and heat loss calculations through to radiators, cylinders, pipework, and controls. The total cost varies significantly depending on the size of the property, the number of rooms, the heat source chosen, and whether the system is a full replacement or a first-time installation. We design every system in-house and provide a clear, itemised quote based on your specific property and requirements, so you always know exactly what you are paying for before any work begins.
The time required to install a full central heating system depends on the size and complexity of your property and the scope of work involved. A standard domestic installation typically takes between three and seven days for our team to complete, though larger properties or more complex projects may take longer. We always provide a realistic timeframe at the quoting stage and aim to complete every installation with minimal disruption to your daily routine. All work is carried out by our own engineers, which means there are no delays caused by coordinating multiple trades.
A central heating system works by generating heat from a single source, whether that is a boiler, heat pump, or other heat generator, and distributing it throughout your home via a network of pipework connected to radiators or underfloor heating. Hot water is circulated from the heat source through the pipework to each radiator or zone, where it releases heat into the room before returning to the heat source to be reheated. A well-designed system with correctly sized radiators and good zoning controls will heat every room evenly and efficiently, keeping running costs as low as possible.
The size of central heating system required for your property depends on a number of factors including the total floor area, the number of rooms, insulation levels, window sizes, and the type of heat source being used. We carry out a full heat loss calculation for every property we work on, assessing each room individually to determine the correct BTU output required. This ensures your system is neither oversized nor undersized, which is critical for efficiency and long-term performance. We never guess when it comes to system sizing.
Common signs that a heating system needs replacing include uneven heat distribution across rooms, radiators that are cold at the top or bottom, frequent breakdowns or repairs, significantly higher energy bills, and a heat source that is more than 15 years old. If your system is struggling to heat your home efficiently or requiring regular attention, a full system assessment is worth considering. We can inspect your existing setup and give you honest advice on whether targeted repairs or a full replacement is the most cost-effective solution for your property.
In many cases, yes. Depending on the condition of your existing pipework and radiators, it may be possible to upgrade specific elements of your heating system rather than replacing it entirely. This could involve fitting a new heat source, replacing undersized or inefficient radiators, upgrading the cylinder, or improving the controls and zoning. We assess every system on its merits and recommend whatever makes the most sense for your property and budget, whether that is a targeted upgrade or a full replacement.
A new central heating system is almost always worth the investment for properties with an ageing or inefficient setup. Modern heating systems, particularly those paired with renewable heat sources like air source or ground source heat pumps, deliver significantly lower running costs, better heat distribution, and greater reliability than older systems. The upfront cost is offset over time by reduced energy bills, and a well-designed new system adds real value to your property. We will always give you an honest assessment of whether a new system makes financial sense for your specific situation.
Yes, every heating system we install is designed entirely in-house by our own engineers. We carry out a full property assessment including heat loss calculations, floor plan review, insulation evaluation, and EPC rating consideration before designing a system that is correctly specified for your home. We never use third-party designers or follow a template approach. Every system is tailored to your property, your budget, and your heating goals, and we will talk you through our recommendations clearly before any work begins.
We specify and install equipment from reputable, industry-leading brands across all elements of a full heating system installation, including radiators, cylinders, controls, and pipework. For heat pump installations we are approved installers for Vaillant and Alpha, two of the most trusted names in renewable heating. We only use products we are confident in and happy to put our name to, and we will always explain our recommendations and the reasons behind them when discussing your system design.
Accredited, insured and only using the best brands
Every installation we carry out uses the best brands and is backed by industry-leading accreditations and full public liability insurance.






Properly designed heating systems by specialist engineers
We take heating system design seriously. Every installation we carry out starts with a proper heat loss calculation and ends with a fully commissioned, balanced system that performs correctly from day one. Our engineers have the technical knowledge to design systems that work, the experience to install them properly, and the honesty to tell you if a different approach would serve your property better. All work is carried out by our own team, with no subcontractors at any stage.
"The team designed and installed a complete new heating system in our Victorian terrace. They did proper heat loss calculations for every room, specified the right radiators, and the whole system was balanced and running perfectly within a week. The difference compared to our old setup is night and day."

A full heating system installation is often the foundation for a wider renewable heating upgrade. Whether you are pairing your new system with an air source heat pump, adding underfloor heating to maximise efficiency, or looking to keep everything running smoothly with regular power flushing and maintenance, we offer the specialist services to complement every heating system installation.

Air source heat pumps
Pairing a new full heating system with a Vaillant or Alpha air source heat pump is one of the most effective ways to reduce long-term running costs. We design and install complete heat pump systems alongside full heating installations for properties across Cumbria and Lancashire.

Underfloor heating
Underfloor heating is an excellent addition to a full heating system installation, particularly in properties with a heat pump. We design and install wet underfloor heating systems for renovations, extensions, and new builds as part of a complete heating system package.
Power flushing
If you are upgrading an existing system rather than replacing it entirely, a power flush before installation can significantly improve circulation and efficiency. We carry out professional power flushing and heating cleans for domestic properties across Cumbria and Lancashire.
