The complete guide with all you need to know about Econcept 51A

Ferroli Econcent 51A is a reliable boiler having a side by side fitted modular installation through master-slave connection. Once you purchase this boiler you won’t have any regrets. The cutting-edge technology allows the user to operate the boiler either by natural gas or LPG. A heating system with a hot storage cylinder or storage tank needs to be installed alongside the boiler for optimum results.

According to Directive 92/42 EEC, this boiler is certified with 4-star efficiency and has also earned a class 5 for NOx emissions certification from Directive EN 297/A5 which makes it fall under the list of A-rated boiler. The cascade options can be used without the need for additional controls.

The reverse micro-flame ceramic burners decrease harmful emissions as well as eliminates the thermal expansions. The aluminum silica heat exchangers are the reason behind the boiler’s high efficiency with extended life. These features make it an ideal unit for large homes or places where hot water requirement is high.

For the comfort of the users throughout the year, an optional probe can be installed externally. This external probe activates the ‘Sliding Temperature’ mode that enables us to control the heating according to our convenience depending on the outdoor weather conditions. The whole system is quite convenient to install and use. A 2-year warranty is provided on the parts and labor can be present on doorsteps in case any difficulty occurs during that particular period.

Thanks Karon. You made things happen quickly and better than I expected. Ferroli are good, but they are very lucky to have you on their staff. Kind, efficient ,organised and dedicated, these are qualities you don’t find very often, bunched all in one single person. I nominate you for the Oscar of customer service.
Will and Dillon, the engineers, young but efficient and knowledgable, polite and helpful. Thank you gentlemen, you can be proud of yourself.
I recommend Ferroli to all. We have 3 boilers installed in our family. And two of my friends followed my advice and had them installed as well.
Merry Christmas to all from Ferroli.

As an installer for 20 years I’m used to hearing about people’s boilers breaking down… but when it’s your own you realise no heating or hot water during the coldest time of year with 2 young kids can be a nightmare. After getting in touch with the company I was put in the safe hands of Jasmin , who went above and beyond the call of duty to locate and distribute the parts I needed, they were dispatched and arrived within 24 hours, installed in no time whatsoever as these boilers are so easy to work on and normal service resumed.
I’ve fitted many of these boilers and have always had great service and quality…tryed and tested by me. Thank you and top marks to jasmin and the rest of ferroli UK.

  • Review:

I moved into my property 19 years ago where a Ferroli boiler was already installed. Within 12 months of being in the property I had an issue with my Ferroli boiler, a local company came out and advised me that I would need a new boiler because my 10 year old boiler was not very efficient and would be far too expensive to repair. I was recently widowed so My Daughter in law advised me to contact Ferroli direct to find out what their costs would be to repair the boiler and if a replacement was really required. A lovely engineer attended and quickly repaired the boiler and advised me that a new boiler was not at all required.

I would like to say that my FERROLI boiler of 29 years is still going strong and all I’ve paid out over this period is for an annual boiler service. I’m sure this boiler is going to out live me but if it doesn’t I will certainly be replacing it with another Ferroli.

I can’t thank them enough
