Down in Portsmouth today to look at a Port Marine source heat pump. (but that is another blog) on the way down we popped into the NAPIT renewable energy training centre to view a renewable energy holly grail (well mine anyway) have been looking for a few years now for a cost-effective, efficient and effective replacement for the hundreds of oil range cookers and heaters we have in the National Trust (Aga, Rayburn, Stanley, Esse and so on). We have unsuccessfully piloted the use of a pellet and wood Lohberger before as can be read in a previous blog. The low heat and hot water output was the issue at the site where it was trailed. We now have another candidate in the Klover 120. The main difference seems to be better control system (the boiler can call on another heat source if required) one fuel type which is pellet (the other stove burned two) and a much simpler overall approach to serviceability
with a combined heat output of 22kw (5 and 17kw) this a few time more than that of the Lohberger. Initial concerns are around the ability to modulate to a low enough level, the lack of hot plate cover (which is being addressed with a retro fit system) the 4″ flue (for cleaning and clarification for building regs but we were informed that the manufacturer had dealt with this)
On the plus side was the cost of around £6k plus instilation and the aspect which sold the pilot was the fact that the stove is undergoing MCS accreditation and we could be looking at RHi income which makes the business case a no brainer. Oh and having an installer in nearby Flint also helps. We now need to make sure the range cooker delivers on the practical day-to-day front. Holly Grail…? Lets see!
