In homes, some appliances and fittings simply last much longer than others. If your London boiler installation was a long time ago, htne you are not alone. In terms of longevity, nothing can possibly beat the humble-but-reliable boiler—a fixture which easily commands over 50% of your energy bills. That said, keeping the boiler in tip-top shape should be of utmost priority, as well as knowing the right time to call for companies that offer professional boiler installation in London for a replacement.
These days, it’s important to note that boiler technology has changed much and that replacement is pretty much the best option if you have an older one. Today’s current models of boilers are far more efficient than older ones, even those which were manufactured as recently as 10 years ago. In addition, temperature control devices have developed during that time, meaning one can now control how he heats an area of the home more precisely.
The time will come when a boiler can never work as well as it used to, and that’s inevitable. Here are a few signs that’ll clearly indicate the need for a replacement:
Temperature Fluctuations – A failing boiler will give a pretty obvious symptom early on: regular fluctuations in temperature and pressure. Once temperatures get too low, too high, or the fluctuations occur far too often, it may indicate mechanical issues deep within the boiler’s inner workings. For instance, fluctuations may occur due to one of two factors: the pilot light can’t stay lit or the safety cut-off mechanism is being triggered by an unknown force. The latter is often indicative of a serious electronic or mechanical issue that demands immediate attention.
Increased Frequency Of Repairs – If the repairman’s been in and out lately to perform some costly repairs, it’s another sure sign. As the boiler approaches its twilight years, repairs switch from “few and far between” to “far too often”. This standard rule of thumb can help in determining frequency: if the repair costs exceed 50 percent the price of a new unit, a replacement from local London boiler installation companies like LB Plumbing & Heating is warranted.
It’s a “Grandpa Boiler” – Age doesn’t necessarily denote frailty, but in the boiler arena, it certainly signifies inefficiency. A boiler installed decades ago when the house was first built is highly likely to be quite inefficient now and can actually suck all the oxygen out from the room, which is a dangerous predicament. Boilers like these are better sent off to retirement.

London Boiler Installation Tips On Bolier Size
Boilers should be sized to supply adequate heat and hot water, and warm the house to the relaxation temperatures that are necessary when the temperature outside is below freezing. (Historically, this has been -1°C although more lately -3°C is being advocated). The heat surplus to requirements is lost through convection via the flue. It is cooled by the cooler air entering at the foundation of the boiler so that it fires-up again if the system will not want any heat then. The boiler is doing what’s referred to as short-cycling. If a boiler is oversized even when it’s freezing outside, the quantity of heat squandered is substantially raised throughout all the warming season.
Additional analysis may be needed to ensure unnecessary over-sizing or under-sizing will not happen. As a rough approximation most flats opting for a London boiler installation, apartments and houses that are smaller, with up to 10 typical size radiators will need a 24 to 27kw Combi Boiler. But for a big house with anything up to 20 typical size radiators a 42kw and a 35kw Combi Boiler would be installed.
