Customer Brief:

For this project, which was undertaken in May 2024, Warmco were asked to heat this brand new, 20,000 sq ft warehouse unit.  We were asked to supply and install four Warmco / Winterwarm high efficiency, suspended, EH25 electric heaters, into this modern, fully insulted, brand new portal framed building.

Features of the Heaing System:

This customer asked Warmco to enable them to heat their brand new warehouse premises and workers.  Specifically, they asked us to keep these storage and distribution premises to 20c when it was minus 3C outside.  They chose to use suspended heaters to free up much-needed floor space.  The EH25 electric heaters can be used to get their spaces up to temperature quickly, but once the thermostatic control panels register that they have achieved the desired temperature, they have the capacity to modulate down from a 25kw maximum to 10kw on low fire (cumulatively 100kw down to 40), to ‘top up’ the heat, making them a 95.9% maximum efficiency.  This modulation feature offers a fuel cost saving of up to 30% against standard non-modulating models of heater.  (These heaters can be carbon neutral and they carry a 2-year parts and one year labour warranty).  I also quoted to install six Winterwarm WCU60 destratification (heat recovery) fans on thermostatic controls.  Each fan was suspended 1m from the roof purlins, to provide two full air changes per hour.  These are high efficiency axial fans which push large volumes of heated air back to the working zone.  The fan operates when the roof space temperature rises and can also provide ‘free heat’ if positioned over lights or machines that generate their own heat.  This can save up to 30% on running costs for the heaters, by reducing the further heating required.  The installation took just four days, during which time our engineers worked hard to create minimal disruption to the customer.

The heater installed by Warmco is absolutely brilliant! It has surpassed our expectations… it is very efficient on gas consumption and overall working with Warmco will save us a lot of money in future. All in all we are over the moon with our heating system and would be very happy to recommend Warmco’s services to anyone.

Warmco were very quick to respond to our request for a survey and to quote for our heating; much faster than the response time that I have generally come to expect form other companies. The engineers communicated well and worked round our site requirements, to create minimal disruption to ourselves and our customers. We are pleased with our heating, it is working well. Warmco have been available to assist with giving advice on our system. Overall, we were very impressed from the start to finish of our dealings with Warmco.

Overall I'm happy with the service provided by Warmco. The site visit and quoting process was good. The install guys were good, on time, seemed to get on with the job and completed it on time with good communications. As for the heaters, as it hasn’t been too cold as yet, I can't comment fully on how effective they are.”

Darrell Freeman – Big Dude Clothing, Ellesmere Port October 2020

Warmco were knowledgeable when it came to recommending a heating system to us. They explained the system in a way that gave us confidence in the products and services they were offering. Most importantly, the price was right. The installation was great, the engineers came when we were told they would, worked round our warehouse operations, did a neat job of the installation and were clean and tidy. We are pleased to say that the heating does exactly what we need it to do.
