Heating Services Andover, Marlborough & Hungerford
Your complete guide to wet-side heating work. From radiator installation and power flushing to wet underfloor heating, central heating pumps and hot water cylinders -- by a qualified, WaterSafe approved local plumber. We don't work on gas or oil, and we'll gladly recommend a trusted Gas Safe engineer for your boiler.
Why Choose a Local Heating Specialist in Andover?
Finding a qualified tradesperson you can trust is essential for keeping your home warm, comfortable, and energy-efficient. Whether you need a new radiator fitted, a power flush, or a wet underfloor heating system installed, working with a local WaterSafe approved plumber means faster response times, better knowledge of local property types, and genuine accountability.
Based in Great Bedwyn (SN8), I serve homeowners across Andover (SP10/SP11), Marlborough (SN8), Hungerford (RG17), and Tidworth (SP9). I look after the wet side of your heating -- radiators, pipework, pumps, hot water cylinders and underfloor heating. I don't work on gas or oil, so if your boiler needs attention I'll happily recommend a trusted Gas Safe engineer. This guide covers everything you need to know about heating work in the area, from spotting common faults to honest pricing.

Heating Services We Provide in Andover, Marlborough & Hungerford
I provide a full range of wet-side domestic heating services. Every job comes with a 12-month workmanship guarantee, transparent pricing, and the reassurance of working with a qualified, insured professional. Please note we don't work on gas or oil boilers -- for those we'll recommend a trusted Gas Safe engineer.
Pumps, Cylinders & Immersion Heaters
I replace failed central heating pumps, fit and repair immersion heaters, and install or swap hot water cylinders -- including unvented (G3) systems such as Megaflo. If you've lost hot water, your pump is noisy or seized, or your cylinder is past its best, I can put it right on the wet side. Anything involving the gas or oil boiler itself is a job for a Gas Safe registered engineer, who I'm glad to recommend.

Radiator Installation & Replacement
Whether you need an additional radiator in a cold room, are upgrading old panel radiators to modern high-output models, or replacing leaking valves, I can help. I fit both standard convector radiators and designer or column radiators, complete with thermostatic radiator valves (TRVs) for individual room temperature control.
Power Flushing
If your radiators have cold spots, your system is noisy, or your boiler keeps losing pressure, sludge buildup is often the cause. Power flushing uses a high-flow pump and specialist chemicals to remove rust, scale, and debris from your entire central heating system. I recommend a power flush every 5-10 years, or before fitting a new boiler to protect it from contamination.
Central Heating Systems
From diagnosing why certain rooms are cold to upgrading your entire central heating system, I handle all aspects of domestic heating. This includes re-piping, zone valve replacement, pump upgrades, magnetic filter installation, and heating controls. I also fit smart thermostats and programmers to give you better control over your heating and reduce energy bills.
Underfloor Heating
Underfloor heating is increasingly popular in Andover and Marlborough homes, particularly in kitchens, bathrooms, and extensions. I install both wet (water-based) and electric underfloor heating systems. Wet systems are ideal for new builds and extensions, while electric systems suit retrofit projects and smaller areas. Both options work well with heat pumps.
Heating System Upgrades
Older heating systems waste energy and cost more to run. I can assess your current setup and recommend cost-effective wet-side upgrades, whether that means fitting a magnetic system filter, replacing a tired central heating pump, adding TRVs throughout the house, or preparing your pipework for a future heat pump. Every upgrade is designed to improve comfort and reduce running costs. Where a new boiler is the answer, I'll point you to a trusted Gas Safe engineer.

Common Heating Problems in Andover & Marlborough Homes
The properties in Andover (SP10/SP11), Marlborough (SN8), and the surrounding villages range from period cottages with original pipework to modern estates like Augusta Park. Each type presents different heating challenges. Here are the most common issues I deal with as a local heating engineer.
Radiators Cold at the Bottom
This is the most common heating complaint I receive from homes in the Andover area. When the lower section of a radiator is cold while the top is warm, it usually indicates sludge buildup inside the radiator. The iron oxide sludge settles at the bottom and prevents water from circulating properly.
The fix: For individual radiators, removing and flushing can help. For system-wide sludge problems, a professional power flush is the most effective solution. I also fit magnetic system filters (such as the MagnaClean) to prevent future sludge buildup.
Boiler Losing Pressure
If you are regularly topping up your boiler pressure via the filling loop, there is a leak somewhere in the system. Common sources include weeping radiator valves, corroded pipe fittings, or a failing expansion vessel within the boiler itself.
The fix: I carry out a systematic pressure test to trace wet-side leaks. In older Andover properties, the culprit is often buried pipework running beneath floorboards -- once located, the repair is usually straightforward and ends the constant inconvenience of pressure loss. If the fault turns out to be inside the boiler (such as a failed expansion vessel), that's one for a Gas Safe registered engineer, who I can recommend.
Uneven Heating Between Rooms
Many homes in Marlborough and the surrounding SN8 villages have been extended over the years. When radiators are added to extensions without properly balancing the system, some rooms overheat while others remain cold. Poor pipe sizing and incorrectly adjusted lockshield valves are typical causes.
The fix: Balancing the system by adjusting the flow rate to each radiator ensures even heat distribution. In some cases, upgrading undersized pipes or adding a larger radiator to a particularly cold room is necessary.
Noisy Boiler or Heating System
Kettling (a rumbling sound like a kettle boiling), banging pipes, or clicking from radiators all indicate problems that should not be ignored. Kettling is usually caused by limescale or sludge buildup on the heat exchanger -- particularly common in hard water areas like Hungerford and the RG17 postcode area.
The fix: Kettling on the boiler's own heat exchanger is one for a Gas Safe registered engineer to assess -- I can recommend a trusted one. For system-wide noise, though, a power flush combined with a scale inhibitor and a magnetic system filter tackles the root cause on the wet side. Banging pipes may simply need clip adjustments to allow for thermal expansion.
Frozen Condensate Pipe
Modern condensing boilers produce acidic condensate that drains through a plastic pipe, usually routed externally. During severe cold spells in our area, this pipe can freeze, causing the boiler to shut down with a fault code. This is a frequent winter call-out across Andover, Tidworth (SP9), and the exposed villages along the Hampshire/Wiltshire border.
The fix: As an emergency measure, pouring warm (not boiling) water over the frozen section can restore operation, and lagging the exposed run helps stop it refreezing. If the condensate pipe needs rerouting or resizing, that's part of the boiler installation and one for a Gas Safe registered engineer -- I can recommend a trusted one.
WaterSafe Approved & Properly Qualified
It is a legal requirement that anyone working on gas appliances in the UK must be registered with the Gas Safe Register. This replaced the old CORGI registration in 2009. As a homeowner, you have the right to ask to see an engineer's Gas Safe ID card before they start any gas work. Rosebourne Plumbing specialises in the wet side of heating and does not carry out gas or oil work -- for that we'll always point you to a trusted Gas Safe registered engineer.

What This Means for You
When you hire a WaterSafe approved, G3 qualified plumber, you know the wet-side work will be carried out safely and to the required standard. For anything involving gas -- such as a boiler service, which by law must be done by a Gas Safe registered engineer -- always check the engineer's Gas Safe ID card, which you can verify on the Gas Safe Register.
My qualifications in unvented hot water (G3) and heat pump cylinders (G1 ASHP) mean I can advise on the wet side of the full range of heating options. Whether you want to upgrade your hot water cylinder, replace a heating pump, or prepare pipework for a future heat pump, I can handle it -- and coordinate with a Gas Safe engineer where the boiler is involved.

When Should You Call a Professional?
Some heating issues are safe to investigate yourself, and some wet-side jobs are ones I can help with. Anything involving gas -- including boiler faults and gas pipework -- must be handled by a qualified Gas Safe registered engineer, not a wet-side plumber. Here is a quick guide to help you decide.
Safe to Check Yourself
- Bleed radiators to release trapped air
- Top up boiler pressure via the filling loop
- Check thermostat batteries and settings
- Reset the boiler (press reset button once)
- Check timer/programmer settings
- Pour warm water on a frozen condensate pipe
Call a Professional
- You smell gas -- call the Gas Emergency line (0800 111 999) first, then a Gas Safe engineer
- Boiler keeps locking out after reset -- one for a Gas Safe engineer
- Black or sooty marks around the boiler -- a Gas Safe engineer must investigate
- Any work involving gas pipework or connections -- Gas Safe registered only
- Persistent pressure loss (weekly top-ups) -- we can trace the wet-side leak
- No hot water despite heating working -- cylinder, immersion or pump
- Radiators remain cold after bleeding -- likely sludge, a job for a power flush
- A failed or noisy central heating pump needs replacing
Heating Efficiency Tips for Andover & Marlborough Homes
With energy prices remaining high, making your heating system more efficient is one of the best investments you can make. Here are practical steps I recommend to homeowners in the Andover and Marlborough area.
Fit TRVs to Every Radiator
Thermostatic radiator valves let you control the temperature in each room individually. Turn down radiators in rooms you do not use regularly, and you could save 10-15% on your heating bills. I supply and fit TRVs from around £35-50 per radiator.
Install a Magnetic Filter
A magnetic system filter (such as MagnaClean or Fernox TF1) sits on the return pipe to your boiler and catches metal debris before it can damage the heat exchanger. This extends boiler life, maintains efficiency, and costs from £150 + VAT installed.
Upgrade Your Controls
Replacing an old mechanical timer with a modern programmable thermostat or smart heating control (such as Hive, Nest, or Tado) gives you much better control over when and how your heating operates. Many offer phone app control so you can adjust heating remotely.
Book an Annual Boiler Service
A serviced boiler runs more efficiently than a neglected one. By law a boiler service must be carried out by a Gas Safe registered engineer, so book one each year -- we can recommend a trusted local engineer. Pair it with a clean, sludge-free system on the wet side and a well-maintained boiler can last 15 years or more.
Power Flush Before a New Boiler
If you are having a new boiler installed, always have the system power flushed first. Fitting a new boiler onto a dirty system can void the manufacturer warranty and cause premature failure of the new heat exchanger.
Insulate Your Pipes
Lagging exposed pipework in unheated areas (lofts, garages, under floors) prevents heat loss and protects against freezing in winter. Pipe insulation is inexpensive and can be fitted quickly -- or you can DIY with foam tube insulation from any hardware shop.
