Hi all, I have a Rheem 38L vertical water heater in my bathroom (appr 8 years old) and recently it has been leaking water thru the evacuation pipe. The leaking starts after the water heater has been switched on for some time (>10min) and does not stop when I switch off the heater and/or use hot water. In the past it was just dripping, but now it is really flowing significantly. The dripping would sometimes stop by itself after few days. Does this necessarily mean that the heater is broken and needs to be replaced, or could it be that there is a problem with a relief valve or smtg like that? Thanks in advance for your help.

Hi all, My current storage heater is leaking and I want to replace it. The current heater is a Rheem 38 liter but 15 or 25 liter will be enough for the new one. Unfortunately the contractor will need to remove a small part of the false ceiling over the sink to access the space. My question is what would be a reasonable price for doing this job: - New storage heater 25L, just a regular brand - Redo any piping work for connection - Redo lowered false ceiling section (appr. 2 x 3 feet) I realize that it is difficult to give an exact estimate, but just a rough estimate would be very helpful. Today contractor who visited quoted me 1140SGD (490 for heater Alpha 25L, ceiling 450, install 200), which sounded absolutely completely ridiculous to me (hopefully it *is* ...)

Thanks for your answers Aron, appreciate it. I have decided to go for Daikin non-inverter system (R22), there was a good offer. Very simple model from very good brand (at least that is what i read everywhere), don't think I can go wrong here. I will have them do pressure test on 2 units (these had leak in compressor), the 3rd one I trust to be okay, it has always been working flawlessly w/o top-up. Am somewhat surprised that concealed piping not designed in such a way that it will at last least 20 years or so (or is it?). Nobody wants the trouble of replacing the concealed piping unless absolutely necessary. What material is used for the piping and what usually makes them leak? PS @ chinpokomon: feel free to hijack, my questions answered :-) good luck!

Hi all, I am new to all this aircon stuff, so I have some general questions, hope you guys can answer some of my questions. My current aircon is Sanyo, non-inverter, a system-2 and a system-3, the latter is broken, repairing is not an option. The aircon uses R22. I live in a condo about 10 years old. My questions: - The piping in my house is concealed, so I assume that it will normally not be replaced when installing new aircon, is that correct? - Will I be able to switch to R410A aircon, or will that not be possible without changing the internal piping? - My system-3 is the one that needs replacement. It has 2 separate compressors in the box, one for the 2 common rooms and one for the MBR. I imagine that this is more efficient when using only one of the rooms. Do all modern non-inverter types have separate compressors or does it depend on the model? - Since I am hardly using the aircon at all, i am considering buying non-inverter. With regards to life-time, is there a difference between inverter vs non-inverter? - What is the target temperature that they normally use to determine the capacity? 18C, 20C, 22C? I usually have it at 25C, does that mean I can do with a lot less capacity than would normally be advised for a space of that size? Thanks in advance for your help!
