Worcester Bosch 30cdi Pump Running All The Time
Worcester Bosch circulating pumps are robust and will give many years of efficient hot water circulation providing that the heating system water is clean and treated with an inhibitor, as a build up of corrosion or sludge within the heating circuit can lead to a pump failing or seizing. All our Worcester Bosch Pumps are new and genuine.
Worcester Greenstar 30CDi Classic Regular Boiler Natural Gas ErP 30kW ErP Condensing Regular Boiler. The Greenstar CDi Classic Regular boilers are Worcester's top performing wall-mounted regular boilers. Their impressive heating outputs make them an excellent choice for installation in larger properties. Heating zone circulator pump wont' stop running: this article explains how to. In these buildings the heating thermostat simply turns the heating boiler's. Reader Question: circulator pump won't stop: the circulator pump stays on all the time.
We installed this boiler earlier this week as a replacement for an 20 + year old Myson 'Midas' combination boiler. It is a Worcester Bosch Greenstar 30CDi. It looks much more interesting with the cover off! We have probably installed more Worcester boilers than any other brand over the years.
It's amazing to see how they have evolved and improved. Whilst it probably looks rather complicated inside to the untrained eye we are very familiar with them and know them inside out.We upgraded the system controls on this installation to current standards. Our customer should now notice a marked reduction in his gas bill.This customer was a second generation referral. A couple of years back our accountant referred us to his brother in law who we done a similar job for. We recently carried out the annual service for him and he mentioned he'd passed our number onto a work colleague which resulted in this job. Hopefully he too will now recommend us and continue the word of mouth cycle.

Are you looking to directly replace the old, regular boiler in your 4-5 bedroom home?Perhaps an engineer has already recommended a 30kw boiler, but you’re not sure of the difference between the Worcester Bosch Greenstar 30cdi and 30ri.I really don’t blame you for feeling confused, as on paper they sound almost identical. However, there ARE a couple of differences.Over the years, many of my customers have asked me for advice when their old regular boilers have packed up, and I’ve used both of these boilers depending on the situation – that’s why I thought there was a real call for this comparison review. IntroductionThe brand Worcester Bosch has a reputation that’s second-to-none when providing the best quality boilers, having won four years running – so both the seem like a very sensible choice.Both of these boilers can make for a quick fix if you’re looking for a direct replacement for your old, regular boiler, and can easily be installed in just 4-5 hours with very minimal upheaval. Obviously there will be extra time to flush system, patch up holes etc.
Basically, all of your radiators, pipework and tank can be left where they are, the boiler replaced and the system quickly flushed out.I know what you’re thinking ‘So, what’s the difference?’I’ve found that the only real difference that really matters with these boilers, is the physical size. Although, it’s wise to mention that the 30cdi is also a slightly newer model, so also has a better range rating. The 30cdi can’t be used with Worcester controls where as the 30ri can if fitted with a Worcester Greenstar wiring centre. Only other difference is the 30cdi has a lift weight of 37.5kg where as the 30ri is a lot lighter at 22.6kg. Output and flow rateWith an output of 30kw to the heating, both of these boilers are best suited to a large 4 – 5 bedroom home with 12 – 14 radiators, and a 200-litre hot water tank – there’s really very minimal difference between them.As they are both regular boilers, they can be fitted with your existing expansion tank and connected to your existing external pump and motorised valves. Ultimately, this can cut down the cost and labour of your installation.However, when connecting to older systems, your chosen engineer must check there are separate cold feed and expansion pipes – these boilers can not be connected to a combined feed and expansion. They are also not compatible with gravity hot water.I also would not recommend connecting to old galvanised steel expansion tank as this will draw dirt, silt and rust into the system.

In this case, it’s better to upgrade the expansion tank. Size and special featuresThe 30ri is a more compact model than the 30cdi, and you’ll find it will quite comfortably fit in a kitchen cupboard without any problems. The 30cdi, being a larger boiler, would have to be fitted in a larger storage cupboard.So, if your current regular boiler is stored in in a kitchen wall cupboard, the difference in size may swing it for you, as the Worcester Bosch Greenstar 30ri would make for the least upheaval.However, if size and location don’t matter, you may wish to opt for the 30cdi, which is the slightly upgraded model and has a better range rating, more settings, and can be fitted with an integral diverter valve. GuaranteeThe good news is that both the 30ri and 30cdi come with Worcester Bosch’s brilliant. The company also has its own dedicated engineers to attend to call-outs, so you know your new boiler is in the best possible hands.Worcester Bosch currently has the best boiler guarantee on the market (in my humble opinion), which is why I recommend them to all my customers.It’s a definite fact that there are longer guarantees out there from other boiler companies, but often you’ll find a catch in the small print, or extra credit card charges before they’ll even agree to a call-out (Vaillant is one exception to this).
