Roger Bisby demonstrates Worcester's Greenskies Solar water heating. The system comprises solar panels, a hot water cylinder and a high efficiency condensing boiler.
I have had Solar Hot water for over 20 year and believe me it WORKS!!! Wouldn't be without it .. Just need a sunny day - even in the wintertime - sometimes I can't touch the return pipe - Even through it isn't that Hot outside!!
Why not have a cylinder above the panels and it will heat via the therm-syphon method which aleviates the expense, unreliability an having to drawa power from the grid of pumps etc.?
Thats not how thermosyphoning works, you need the tank under the panels so when the hotter water expands it becomes less dense and therefore rises up into the solar panels to be heated its then fed back into the bottom of the storage tank for the cycle to repeat.
@@shmoostead5419 No, Hot air rises, so does hot water, therefore pushing the cooler water from the lower pipe on the tank, to the bottom of the flate plate or Evac.tube manifold again.to re process, ..Your theory can work but less efficient...
So what happens if the tank gets up to 65 and the pump shuts off? Won't the water in the panel boil on a red hot day? I assume the system is under pressure, thus raising the boiling point.... but yeah, just a thought.
@@SkillBuilder cool, I thought that would be the case. So realistically, what sort of temps could the panel get to when the fluid is static and under pressure? 120? 130c?
Given how he has endlessly discussed Heat Pumps of all kinds on the Skill Builder channel - and I've watched several of them - I already know that you've completely missed his point. You cannot say that a heat pump is useless: is your fridge/freezer useless? No? Then Heat Pumps aren't useless. Inefficient? That depends on what your datum is really. Roger's point with Heat Pumps has always been that the way that they are all too often implemented means that using them becomes like fighting a losing battle, however, with the proper design implementation they work exactly as you would expect them to.
@@josephmcmahon7470 the fact of the matter is they are not feasible in majority of British homes. If you want to be pedantic, then yes, a heat pump can be efficient. There, does that make you feel better?
@@ssss-df5qz If you're going to discuss topics like this then do it properly. Otherwise you're just holding the whole transition back. Yes, our home Energy Efficiencies are much lower in the UK compared to other countries. This has an effect on how useful an installed Heat Pump can be. Seems to me that the problem is the house/way the pump is installed, not the pump itself. See the major change in focus there?
Oh my days. Roger is everywhere!!

So hang on, buying a house with one of these, does it heat the radiators also???
@@HBOMB-nl9pw - No! Hand washing .... And good to have an Immersun Unit to use solar voltaic to heat the immersion heater - Improve top temp
Does anyone know how to find an installer, because the Worcester website does not recommend any?
Good old Roger....

Where do you want to put the cylinder, in the sky on sky hooks. 🤣
@@copperskills3973 10 years..wow..Most cylinders here are attached above the solar panels..
Thats not how thermosyphoning works, you need the tank under the panels so when the hotter water expands it becomes less dense and therefore rises up into the solar panels to be heated its then fed back into the bottom of the storage tank for the cycle to repeat.
@@copperskills3973 The units are built like that..

With 20% sun in the winter it will take a week to get to 55 degree !!!
But it's s good sales video 😌
Heating luke warm water is cheap as chips compared to heating cold water.
I have a large system. Saving me about 750 quid a year
Lol , plumber friendly ,
and proceeds to jump up and down on the solar collector .

It won't boil if the pressure is there and the hotter it gets the higher the pressure.
@@SkillBuilder cool, I thought that would be the case.

PRV, Pressure Release Valve..
Have USP back up for pump.
Or get garden hose and wet panels. Evaporation cools them massively
@@SkillBuilder The expansion vessel and PRV prevent the pressure build up due to temperature.
Just saw Roger in the Daily Mail talking about the white elephant that is heat pumps and how inefficient and useless they are.

How much cost for a system?
5-6K In UK I believe
