Rated 5 out of 5 by from Neat Hot Water Cylinder This was purchased to run off my Photovoltaic Microgenerator system. The two built-in immersion heaters provided options for 6 kW, 3kW or even 1.5kW input. The lower 3Kw heater provides sufficient power to fully heat the total 250 litres water and then easliy maintain 65 degrees C without problems. There is more than enough hot water for a large family house.

What is the difference between this and the cheaper Prostel Cylinder?

At first glance, and even after looking at the brochures, I can't yet see what the differences are between this and the cheaper cylinder at http://www.screwfix.com/p/rm-prostel-unvented-indirect-cylinder-250-litre/78719 … what does the extra £70 get me?
Asked by: Gallafent
Hi. The only difference is the brand and insulation in a direct stelflow vs a direct Prostel. The direct Stelflow has superior insulation in comparison to a direct Prostel. I hope this helps.
