We are at the stage of our construction when we are deciding on our hot water source.
So far, solar seems to be pricing out pretty high.
Electricity is more expensive here on the Pacific coast, so on- demand electric doesn’t add up either.
In Florida we built using propane on-demand after doing a lot of research.
We saw someone using the a propane set up in the Osa, but that was more out of necessity then anything else.
Does it make sense here in CR to install on-demand propane hot water?
Thanks.Like the cost of electricity, the cost of propane is controlled by the government based upon market conditions. It could go up; it could go down. Generally, it seems like a better solution, at least as far as operating costs are concerned, to use propane rather than electricity.
All that said, I would encourage you to reconsider the life-cycle costs of electricity or propane as compared to a solar system with a 240VAC back element. Our solar water heating system in Lansing, Michigan was installed in 1980 and continues to function today. It has offset an enormous amount (and cost) of energy.
Go for it. We use it and are quite happy. No real investment needed. The on-demand unit of 5 liters costs under $100 and 12 liter unit about twice as much (I’d go with the later).
The most popular brand is “Gines” (that’s what we have). It’s very easy to install as well.
2 tanks (cylinders) of 25 liter (buy second-hand for $10 each). Each refill costs $18 at this time. Gas price goes up and down all the time, but so far stayed below $20 per 25 l tank.
The second tank so that you have a spare in case you don’t want to rush to the store if you run out of gas.Most pulperias (grocery stores) have full tanks readily available. You bring them your empty tank and they exchange it for full one (well, plus 9 mil for the gas).
You will save A LOT of $$ going with gas as oppose to electric, especially at the beach where you’ll have to use air-conditioner a lot.
We too have the Gines unit, purchased from Rojas y Hijos in Grecia. We love the unit which has terrific delivery and efficiency. We use one medium-sized tank per five weeks.
When it becomes necessary, we will replace our electric dryer with a propane unit.Love those great, hot showers!!!
Me too…
I have Gines unit in our vacation home and it’s been terrific…
