Service overview
Radiator work covers more ground than most people expect: replacing tired radiators with modern higher-output panels, adding a radiator to a room that never had one, moving one to make space for a kitchen or wardrobe run, upgrading to vertical or designer panels where wall space is short, and fitting heated towel rails in bathrooms.
The part that determines whether you are happy afterwards is sizing. A radiator has an output rating, and a room has a heat requirement based on its size, its external walls, its glazing and its insulation. Fit a radiator below the room's requirement and it will never get the room to temperature no matter how long the heating runs.
Rusupo Heating and Plumbing Ltd carries out radiator work as part of the wider heating system, not in isolation. That means checking the system can deliver the flow, adding valves correctly, protecting the water quality with inhibitor, and re-balancing afterwards so the new radiator does not steal flow from everything else.
The cost of waiting
A radiator that is cold at the bottom is full of magnetite sludge. That sludge did not appear from nowhere and it is not confined to that radiator, it is circulating through the whole system, and it is heading for the pump and the boiler's heat exchanger. Leaving it means the eventual repair is a boiler component, not a radiator.
Corroded radiators leak, and they rarely leak conveniently. A pinhole above a wooden floor or a downstairs ceiling turns a straightforward radiator change into a flooring or plastering job. The visible rust streak below a valve is a warning, not a cosmetic issue.
There is also the running cost. If one room is under-heated, the usual response is to raise the thermostat, which overheats every other room in the house for as long as the heating is on. Fixing the undersized radiator is almost always cheaper than paying to overheat the rest of the property all winter.
Our process
We look at the room, the existing radiator, pipework positions and the rest of the system, and size the replacement against the room's actual heat requirement.
A free fixed price covering the radiator, valves, any pipework alteration and system treatment, typically back with you within 24 hours.
System isolated and drained down only as far as necessary, the old radiator removed cleanly, and the working area protected.
New radiator hung and fitted with appropriate valves, pipework adapted or extended where the position changes, and all joints pressure-tested.
System refilled, dosed with inhibitor, air purged, every radiator balanced, and the work covered by our 6-month workmanship guarantee.
What you get
Output matched to the room's heat requirement, so you stop compensating by overheating the rest of the house.
Every radiator balanced after the work, so flow is shared correctly and the far end of the system is not starved.
Inhibitor dosed on refill and filter condition checked, so the work does not quietly accelerate internal corrosion.
Vertical, low-level and designer panels, or a relocation, to free up the wall you actually want to use.
Areas protected, water contained and sites left clean: the point our Checkatrade reviews mention most often.
6-month workmanship guarantee and £2,000,000 public liability insurance on every job.
In detail
Standard steel panel radiators are specified by type, single panel, single panel with convector fins, double panel with double convectors, and by height and length. Two radiators of identical size can have very different outputs depending on panel and fin configuration, which is why the specification matters more than the visible dimensions.
Vertical radiators solve the wall-space problem in hallways, kitchens and narrow rooms, though they generally need careful sizing because the available output for a given wall area differs from a horizontal panel. Designer and column radiators bring a different aesthetic and are common in period properties around Essex, where a modern white panel would look out of place.
Heated towel rails are standard in bathrooms but have modest heat output. In a colder bathroom, or one with a large window, a towel rail alone often will not do the job, and we will say so before fitting rather than after.
Every radiator except the one in the room containing the main thermostat should have a thermostatic radiator valve, allowing each room to be set independently. The lockshield valve at the other end is the balancing valve, and it is the one that determines whether flow is shared fairly across the system.
Balancing means adjusting those lockshields so the temperature drop across each radiator is correct and every room comes up to temperature at a similar rate. It is skipped surprisingly often, and it is the difference between a system that works and one that leaves the far bedroom cold.
Valve style also matters practically: angled, straight and corner valves suit different pipe entries, and where pipework comes through the floor rather than the wall the valve choice affects both appearance and future serviceability.
Moving a radiator means moving pipework, which is where most of the actual work sits. Depending on the floor construction, that can mean lifting boards, running new legs, or routing through a different wall. We plan the route at survey so the price reflects the real job.
Adding radiators, for an extension, loft conversion or garden room on the same system, increases the total demand. Before quoting we check that the boiler output and the pipework can support the addition. Where they cannot, we say so, and quote the alternative rather than fitting something that will disappoint you.
Where a radiator is being removed entirely, the circuit needs capping properly rather than leaving a dead leg, and the system needs re-balancing afterwards for the same reason as any other change.
We fit and replace radiators in Braintree, Colchester, Kelvedon, Tiptree, Feering, Halstead, Sudbury, Sible Hedingham, Coggeshall and the villages around them. Much of the older housing stock in this area has solid walls and high heat losses, which is exactly the situation where an inherited undersized radiator produces a permanently cold room.
Radiator work also sits naturally alongside other jobs: a powerflush when the system is heavily sludged, a boiler replacement when the appliance is at end of life, or bathroom work where a towel rail is going in. Where combining jobs saves you a second visit, we will say so.

Questions
Something not covered here? Call 07984 042373: the 24-hour line is usually answered personally by Matt.
Each job is quoted as a fixed price covering the radiator, valves, any pipework changes and the system treatment on refill. The quote is free and priced on the difficulty of the work rather than an hourly rate.
A straightforward like-for-like swap is usually a short single visit. Relocations, additions and multiple radiators take longer because the pipework is the real work: your quote will state the expected time.
Usually not immediately. Cold at the bottom means sludge build-up, which is a system problem. A powerflush frequently restores those radiators; where a radiator is badly corroded internally, replacement is the better answer. We will tell you which after looking at it.
Yes, provided the boiler output and pipework can support the extra demand. We check that before quoting rather than after fitting, and if the system cannot take it we will explain what would be required.
Yes. It involves altering or extending the pipework, which may mean lifting floorboards depending on the construction. We plan the route at survey so the quoted price is the price.
Yes, always. Balancing every radiator after the work is part of the job, without it, the new radiator can take flow away from rooms at the far end of the system.
In a system that is kept clean, correctly inhibited and fitted with a magnetic filter, radiators last a very long time. What shortens their life is internal corrosion caused by untreated system water and repeated draining and refilling without inhibitor.
Yes, along with heated towel rails and column radiators. The important step is checking the output of the chosen model against the room requirement before it is ordered.
Isolate both valves if you can and put something under the leak. We run 24-hour emergency cover across Essex and Suffolk, usually answered personally, with typical response within the hour.
Yes, plus Kelvedon, Tiptree, Feering, Halstead, Sudbury, Sible Hedingham, Coggeshall and the surrounding villages.
