hi
i just installed the panasonic dh-3ndp1 water heater with pump. it is working well, the pressure is a bit low even with the pump. however ,i find that the LCD display is very dim. is it normal? or is the any setting can be done? I kinda regret buying the pump version, there is no way to control the heater and the pump separately..sometimes i just need the heater without the pump.. too bad.. |

hi all
Currently my house have a booster pump, and the water heater itself have dc pump? If I power on the booster pump, will it damage the water heater DC pump? Thanks  |

QUOTE(ceo684 @ Nov 8 2019, 11:27 AM) If you use the main booster pump then don't turn the WH pump on, afraid that two pumps will cause over pressure (unless you are using rain shower). that's the problem,I cannot turn off the WH pump, it's one switch that control the heater and pump together. The booster pump output is around 4bar, the WH input is 3.8bar... You can check the pressure rating on the booster pump OUTPUT, as long as this pressure within the INPUT pressure range of the WH you are OK.   |
