Hoo boy...what an off-topic clusterfreak this thread has become! Might as well add to it... I have to disagree with the US as the be-all, end-all of origin and influence. At least that was not the case when I lived in Singapore and Indonesia. For example, US diesel vehicles do not meet emissions requirements for Singapore. Toyota, Isusu, and Mitsubishi dominate the market there. Just like many European countries, all three use particulate traps for thier diesel engines. You will not see a smoking diesel auto, truck, or bus in Singapore. Some US autos can't be sold in S'pore because of the brakelights and turn signals. They require that rear turn signals use a completely seperate bulb from the brake lights. in addition, rear turn signals must be amber. This is a safety protocol inherited from Europe. US banks also have trouble in the Singapore market. The Lion City has adopted EU guidelines for customer privacy that US firms simply could not stomach. Such laws cut down junk mail and reduce the chance of identity theft. Then there is the mobile phone market. US-based standards such as CDMA are virtually unheard of in Asia. The European GSM standard rules, and for good reason. GSM requires the least battery power to produce a usable signal. There is US influence in Asia, to be sure. However, it is not the prime-mover some people would believe. And to our friends from the Great White North... My furnace install has a few components from Canada. The 13ga, 275 gallon Crown oil tank (no relation whatsoever to Crown Boiler Company) I picked up from the Big Orange Box was made in New Brunswick. The 24ga black T's and black solid 90° elbow for the flue I bought at a local hardware store were made in Canada. A flue cover plate, as well as some of the assorted hardware I needed, was also Canadian made. Lot's of things come from, or are influenced by, the American market. Unless you have lived abroad, however, you may be tempted to overrate the effect. Peace. Marco

Most likely, 1.25" would be ideal for a 400K unit up to the outside of the heater, then it's drops to the 3/4" pipe for the regulator in the heater. I'd take the Sta-Rite over a Jandy. Scott

Mounting the remote outside makes absolutely no sense. The purpose of the "remote" is to allow changing the temp setting at one (or more if there are multiple remotes) of the hot water usage locations inside the house. I typically see them mounted in the master bathroom. Tankless water heaters operate at best efficiency when the setpoint is AT the desired hot water temperature for a given task and only the hot water tap is run, for showering for example. I don't have a remote but my tankless is in a broom closet in my laundry room adjacent to the kitchen so is easily accessible for adjustment. I keep it set at 103°F as the normal temp (for showering) and raise it temporarily for other tasks such as handwashing dishes or laundry. Most people run a higher setpoint for "normal" use and perhaps would lower it for showering, thus having the remote in their bathroom.

Cheri Rymerson first post about 12k BTU ac/ heater of unknown brand/model: "How. Ugh is the thru the wall kit for my appliance and when can I get it" Ugh is a written expression of disgust. How disgusting is the thru the wall kit for your appliance ... I can't provide an opinion on that without seeing it. When can you get it ... I don't know anything about that, either. Cheri Rymerson second post about 12k BTU ac/ heater still of known brand/model: "Where is the KIT for holding the unit in the wall????" Guessing ... - Left behind at the store of purchase? - Isn't included with the unknown brand/model? - Not needed for the unknown brand/model per the installation instructions that we can't reference because the brand/model is not stated in the question? - Not available for the unknown brand/model because it's designed only for window installation? Questions for Cheri Rymerson: - What is the brand and model of the unit? - Assuming a through-the-wall kit is required, have you checked with the store where you bought the unit for assistance in obtaining it?
