   Bill, try asking one question at a time to start your thread.

   THere are outdoor on-demand water heaters. If you have a storage tank, you don't want to have it outdoors. Run a web search on on-demand and water heaters and you will find them.

   Radiant heating is not the same as baseboard heating. Baseboards work by convection - for the most part - in floor and under floor work by radiant. Panel rads are in between: some say 50% radiant and 50% convection.

   What is it that you asking ?

   *This unit sits outside The unit is no longer made The separate storage tank sits inside. It has a heat exchanger. The company only has 3 propane units left WE want to heat with this unit using pex tubing using baseboard units like I have pictures an info on from company. I know we need to order book from Radiant Panel association. We also need to do heat loss calculations ,etc. We want to heat for now with those units that run around baseboard. Can not we add pex later under the subfloor? Trying to pay as we go way. So has anyone had an experience with THIS UNIT called THE SEAHORSE? Forget the jokes guys We are talking about spending money hard earned retirement money? Thanks Jean Roberts

   *Bill and Jean,I don't know anything about the Seahorse system you are considering. I would, however, submit that if they are not making them anymore there is a reason and I would be cautious. I have a cabin and I winterize it after each of my winter visits. For me, it does not make sense to pay to heat the building when I am not there. I have winterizing down to a science and it only takes me 15 or 20 minutes to drain and about 5 minutes to open up. I have a propane furnace and an electric stove and hot water heater. What works for me may not be right for you. Remember, however, that if your heating system is dependent on electricity for ignition or distribution winterizing is a sound precaution against outages. I do have a couple of sugestions that I will offer with the understanding that if you don't care for what I say you will not shove it back in my face. Start by reading the article at http://www.jlconline.com/jlc/archive/energy/water_heater_heat/index.html . Consider installing a high efficiency propane water heater to heat your domestic hot water and provide heat. High efficiency units vent through the wall. You will not require a roof penetration or chimney. If you want to put off installing infloor radiant heat you may be able to rig up a water to air heat exchanger (looks like a car radiator) and fan. If you have AC ductwork you may be able to use it to distribute heat from the exchanger.You could also run a water to air heat exchanger off your current high efficiency electric water heater. Unless you are getting your power from Bonniville Power or the TVA this will be a expensive option. Then again, it may be a good short term option. I suspect your propane supplier does not want to risk bringing in a tank over winter roads. I use a 100 pound cylinder. It will keep me going for a week to ten days which is about as long as I stay in the woods. Propane sort of boils in the tank and the vapor passes out under pressure. The colder it gets the less it boils. At colder temperatures you need more surface (in the tank) to generate an adequate flow of vapor. This is why regular propane tanks are long (hot dog shapped) and not tall. If you are in a very cold area you may need two or three cylinders connected by a manifold to generate sufficient vapor.Cylinders can be a pain. You have to take them in for filling and when filled they are a bear to handle. Some folks bring there cylinders inside during the winter so they will stay warm (and generate more vapor). Not smart.Good luck.Steve

   Has anyone out there had any experience with the Seahorse outdoor mounted water heater? It is a heat exchanger without the storage tank. We have no heat now just fireplaces. We had to winterize again today when we left our lakehouse Would like to use radiant under floor heating radiant baseboard using this water heater Prpane company said they could not install a 400 gallon propane tank last of December. What kind of storage tank would be best? we want to keep our electric lifetime water heater for now. I do not want to put in a chimney or a vent for a regular propane unit Called the manufacture they just stopped making the units They sold them all to Bradford White They will not sell directly to us We have to buy from local plbg. supply here. Going to order books from Radiant Panel Association. Anyone had any experience eith Hydronics Alternatives? What about their aluminum baseboard radiators? Thanks
