Each room has a specific heat demand determined by its size, insulation, glazing, and exposure. A radiator that is too small will never heat the room adequately, no matter how long you leave the heating on. One that is too large wastes energy and creates uncomfortable temperature swings. At Conroy Plumbing & Heating, we calculate the BTU requirement for each room before recommending a radiator. This means you get even, comfortable warmth — not a vague improvement that still leaves cold spots. We fit all types: standard panel convectors, compact radiators, vertical designer radiators, column radiators, towel rails, and low-surface-temperature models for schools and care homes. Each installation includes thermostatic radiator valves for individual room control. Whether you are adding radiators to a cold extension, replacing corroded units, or upgrading for better efficiency, we handle the pipework, connections, balancing, and commissioning as a complete service. ## Real Work Examples ![Dark cast iron column radiator installed with antique brass valves](/images/work-2.jpg) ![Close-up of radiator valve and copper pipework connection](/images/work-17.jpg) ![White column radiator installed with copper pipework and chrome valves](/images/work-18.jpg) ## Why the Wrong Radiator Costs You More Than You Think Installing a radiator without calculating heat demand is guesswork — and guesswork costs money. An undersized radiator forces your boiler to run longer trying to reach the set temperature, burning more gas for less comfort. Your thermostat keeps calling for heat because the room never reaches target. - Undersized radiators increase gas consumption because the boiler runs longer trying to reach temperature - Oversized radiators create uncomfortable temperature spikes and cause the boiler to short-cycle - Radiators without TRVs cannot be controlled room-by-room — heating empty rooms wastes energy - Corroded radiators leak slowly, damaging flooring and causing pressure loss in the system - Poorly positioned radiators create cold draughts and uneven air circulation - Old single-panel radiators output 40-60% less heat than modern double-panel convectors of the same size ## How We Install Radiators 1 ### Room Assessment We measure the room, assess insulation, glazing, and exposure, and calculate the exact BTU output required. This determines the radiator size and type. 2 ### Radiator Selection Based on the calculation, we recommend radiators that meet the heat demand and suit the room's layout and aesthetics. We discuss options including panel, column, vertical, and designer styles. 3 ### Installation We fit the radiator with new brackets, valves, and connections. If additional pipework is needed, we route it neatly — under floors or along skirting to minimise visual impact. 4 ### System Integration The new radiator is connected to your existing system, filled, and bled. We fit a thermostatic radiator valve for room-by-room temperature control. 5 ### Balancing We rebalance the entire system to ensure the new radiator receives the correct flow rate without starving existing radiators. This step is critical and often skipped by less thorough installers. ## Benefits of Professional Radiator Installation ### Correctly Sized Every radiator is matched to the room's actual heat demand using BTU calculations — no guessing, no cold rooms. ### Full System Balancing After installation, we rebalance the entire system so every radiator receives the correct flow. No radiator is starved or flooded. ### TRVs for Control Thermostatic radiator valves on every unit give you independent temperature control in each room — reducing waste and improving comfort. ### Neat Pipework We route new pipework under floors or along skirting, keeping the installation clean and unobtrusive. ### All Styles Available Panel, column, vertical, designer, towel rails — we fit the style that matches your room and your taste. ### Guaranteed Work All installations carry a guarantee on parts and labour. The radiator performs as designed, or we make it right.

To calculate the requirement, we multiply room volume by a factor determined by insulation quality, window type, number of external walls, and room usage. A well-insulated living room needs roughly 40-50 BTU per cubic foot. A poorly insulated room with large windows may need 60-70 BTU per cubic foot. Getting this right is the difference between a warm room and a frustrating cold spot. ### Radiator Types and Their Applications Double-panel double-convector (Type 22) radiators are the standard choice for most rooms — they offer high output in a compact footprint. Single-panel (Type 11) models work well in small rooms or hallways. Vertical radiators save wall space in narrow rooms. Column radiators suit period properties. Low-surface-temperature radiators are required in certain settings to prevent burns. Towel rails combine heating with bathroom functionality. ### Positioning for Maximum Efficiency Ideally, radiators should be placed under windows. The rising warm air from the radiator counteracts the falling cold air from the glass, creating even air circulation. Where window placement is not possible (e.g. furniture layouts or floor-to-ceiling glazing), we position radiators on the coldest wall to achieve similar air mixing. ### Replacing Old Radiators If you are replacing corroded or inefficient radiators, a modern Type 22 radiator of the same physical dimensions will typically output 30-60% more heat than an old single-panel model. This means you may be able to fit a smaller, neater radiator that still heats the room better than the original — freeing up wall space. ### Adding Radiators to Existing Systems Adding radiators to an existing system requires checking that the boiler and pump can handle the additional demand. If the total heat load exceeds the boiler's output, adding radiators will reduce performance across the entire system. We check capacity before recommending additions and advise on any upgrades needed. ## Frequently Asked Questions ### How much does it cost to install a radiator? ### Can you add a radiator to an existing system? ### How long does a radiator installation take? ### Do I need to drain the whole system? ### What size radiator do I need? ### Can you fit designer or vertical radiators? ### Will a new radiator reduce my energy bills? ### Do you fit towel radiators in bathrooms?
