Description

The water isn't hot enough. What do I do? Slow down the water flow. Lower flow rate = Higher temperature. Can I use this for a SHOWER? NO. This is for SINKS ONLY (hand/dish washing). It does not have enough power for a shower. Is this good for an RV kitchen sink? Yes, perfect for RVs! It's great for washing dishes or hands in an RV, camper, or garage where you don't need huge amounts of hot water. Just ensure your RV's electrical system can handle the 3000W load How hot does the water get? The temperature depends on the water flow rate. In winter (inlet water ~5°C), you must reduce the water flow to get warm water. What size represent the fittings? The unit uses standard 1/2" NPT fittings.

Nice unit, but beware of electrical requirements
This water heater was purchased to use in a utility sink in the shop. It seemed like the perfect plug-and-play solution, except that the plugging part was an issue. As another reviewer noted, at 110V, a 30 amp fuse is required, which is not standard wiring in many situations. We had a similar experience as the other reviewer in that the unit worked great for a minute or so, water heated nicely, and then tripped the breaker. The local electrical supply store helped us troubleshoot a few options including rewiring the circuit with a 30 amp fuse, or using the 220V outlet and rewiring the plug on the heater unit itself. Either way, it appears that the power cord is only rated to 15amps so neither were feasible options. For what was supposed to be a simple solution to our hot water needs, that all seemed like more trouble than it was worth and made an affordable solution much less affordable. It would be beneficial to all if the product description was more specific about the requirements, or if the product was made to work with standard wiring configurations. If you have the right energy supply situation, it seems like it could be a great unit. ... show more
