That was 12 yrs ago, and nothing in photo albums of it.  Wife out at the moment, IF she has receipts somewhere, I'll look and see if it's noted.   That's a big if though.

@CapraIbex sorry, didn't save any paperwork from that house.

Listen up @CapraIbex. By the time you've weighed up all the possible options. Figured out the logistics. Done all the costings. Found a suitable person to do the installation (that's probably your biggest challenge) the cold spell will be over and you'll have forgotten all about it. 

 

I've been going through this every winter for the last 5 years. What I do now is to wait until the afternoon when the water and the air temp is at its peak, man up a bit and just get done with. I only take one shower a day when the weather is cool like this so it's no problem for me.

That may work for you and your plumbing. With us it doesn’t as the storage tank is in the roof so daily temperature changes have no noticeable effect

Yes, that would be a problem. Our water comes straight from the main supply. No tank, no pump. So for us it works. There's something to be said for simplicity at times.

I agree that sometimes simplicity is good, however our tanks and plumbing means that we can virtually never be unable to get water. It would have to be over a month of the village water being cut. We also are always able to shower. It would have to be several days of power-cut to exhaust the ready-use tank in the roof. So the one downside is that the roof tank isn’t sun warmed, but we could add a tank on a flat roof we have and connect the already installed warm water plumbing.

I would be far more likely to get round to making a passive solar heated system, I already have a design and some of the plumbing, it is just my supply of rountuits has never got high enough to be top priority.

 

All in all the benefits of my setup vastly outweigh the single downside.

That is certainly one reasonable way to power them. However a non electric version would probably be far more economical hear due to hot sun.

 

One could go that way but the cost difference is massive.

That is an incorrect statement. I have a design, copied from a Nepalese builder that is around ฿15,000 for the deluxe version, probably under ฿10,000 for a smaller one.

 

You are probably basing your assumption of cost on the use of vacuum tube versions that are required in higher latitudes and are north of ฿60,000.

 

We are in a latitude where a far more simple, probable un-pumped, setup can do an adequate job.

Never checking solar water heaters that vacuum tube term was head scratching until look up such water heaters.  These were my visions.

I can virtually guarantee there is no functional difference, it is just the form factor

Ordered one of each and paid the heaters yesterday morning of Boonthavorn via lazada. They just advised the delivery will be this afternoon. A surprising quick and efficient process from ordering to delivery.

Guys, we really have moved off-topic here.

 

But I suggest a new thread in Alternative Energy may be useful, we've not had a decent water-heating thread for a while.
