The WORCESTER 87161066860 HEAT EXCHANGER 10 PLATE is a genuine, brand new Worcester product, covered by a Worcester manufacturer's guarantee. To replace the hydraulic assembly you will need to drain the boiler and isolate the cold water supply Boiler leaks usually happen due to blown pump seals. This happens when the seals degrade over time, or experience excessive stress, such as a recent increase in flow rate on the pump.

This primary heat exchanger is guaranteed against faulty materials or workmanship for a period of 120 calendar months from the date of installation subject to the following conditions and exceptions. Various boiler issues are indicated by alphanumeric error codes, all which start with “EA” and conclude with a series of numbers. If the system is an open vent type the feed and expansion pipework must be correctly located relative to the circulating pump so that a positive system pressure is created. A close coupled feed and expansion pipework arrangement must be used wherever possible, connecting into a horizontal run of pipe immediately before the circulating pump.For most Worcester boilers, problems should be few and far in between. Something breaking isn’t necessarily a representative example of the brand’s overall quality — but it can still happen. If yours malfunctions, however, we hope that this guide has supplied enough information to get you started. That the householder may be asked to prove the date of installation, that the appliance was correctly commissioned and that the annual service has been completed to manufactures requirements to the satisfaction of Bosch Thermotechnology Ltd, when requested. You’ll need to insulate the condensate pipe using lagging. Normal lagging will do, but ArmaFlex lagging offers much better protection. #2 – Worcester Boiler — No Hot Water If your boiler is out of warranty and needs a diverter valve replacing, it might be wise to invest that cash in a new appliance with a long boiler warranty. The cheapest place to find a replacement Worcester Bosch boiler online currently is Heatable, where these boilers are usually offered at competitive prices and with 10-year warranties.

The circuit must be designed so to achieve a temperature differential between the heating flow and return of approximately 20ºC for condensing. Service and maintenance Worcester Greenstar 24i Junior combination boiler is leaking from underneath and the central heating stopped working: You most likely control your boiler via a thermostat, or a smartphone companion app. If your boiler rebels and stops obeying your commands, you’re looking at several possible causes:

Create a DHW demand andfully open a tap. Measure thevoltage across the two tags onthe modulating gas valve.Is it over 10Vdc? On the early Worcester Greenstar range the Junior and Si(and Ri) had a condensate trap. The condensate traps job is to safely collect and release the condensation created by a condensing boiler. On later Junior and Si models this was upgraded to a better type of trap which Worcester likes to refer to as a Siphon. There are plenty of reasons a Worcester boiler (or any boiler, really) may not fire up, but most have to do either with gas supply, ignition, or an inability to operate safely.

In most cases, fixing the underlying problems will require the assistance of a Gas Safe registered engineer. How do I reset my Worcester boiler? Alternatively, it could be because the heat exchanger suffers from limescale build-up, and your boiler is ketting. Common Worcester Boiler Issues — What’s Next?If you find that this light isn’t working properly — and neither is the boiler — it could be due to these root causes: With most Worcester Bosch boiler models, resetting the boiler is as easy as pressing and holding the reset button for about 3-5 seconds. The button is typically located on the boiler control panel.

However, if your other gas appliances are functioning well, you should call a Gas Safe engineer to inspect your boiler and determine the underlying issue. They can replace a broken thermocouple and/or remove carbon deposits from the pilot light. In either scenario, this isn’t a DIY-type job.Mind you, we don’t necessarily mean a leak in the boiler itself. Any leak throughout your central heating will cause a boiler to show a dropping pressure gauge. This could be a pin-hole in a radiator, a loose connection on a rad valve, or even a weak soldering joint on the copper pipe. Product Information: There are two kinds of heat exchanger that can be within your heating unit, the primary heat exchanger and the secondary heat exchanger. The primary is present in almost all boilers and it allows the heat to be transferred from the burner to the water within the system. The secondary heat exchanger only appears on combination boilers and allows the heat to be transferred from one closed system to another. If your boiler problems relate to loud banging noises (aka boiler kettling), the 2 most common causes are:
