What boosting options are there?
There are a couple of different options for boosting with this model NS-200 CLASSIC SHWS.
1. Purchase a 25 or 50L electric HWS like a Rinnai Hotflo 25/50 (or similar) and you plumb the SHWS hot OUT to the Hotflo cold IN, effectively running solar hot water from the solar through the Hotflo. If the water from the SHWS is below 50 deg, the electric will kick in and boost it to temperature.
This is a simple and cost effective way of boosting as the Hotflo can plug directly into any 10amp electric powerpoint and only requires minimal plumbing.
2. Gas boosting – plumbing the SHWS to a Rinnai Infinity (or similar, mains or LPG) instant gas hot water system (IGHWS)
– Mains COLD to SHWS IN
– HOT SHWS to cold IGHWS
When the water running through the IGHWS is below 50 deg it will kick in too boost it.
1. is cheaper to install
2. is cheaper over long term
Cost to install varies.
From general feedback installation ranges around $1000 – $1500.
This cost will differ;
– how much is pre-assembled
– installed
– electric/gas
– one storey or more
– NS Installation kit or plumber kits it out.
The NS200WB has an inbuilt electric element option which only requires electrician wiring to a 10amp outlet, it also has inputs to use with a wet-back or retrofit flue (NS-WF1K) which can attach to a combustion heater effectively heating the SHWS when the stove is burning.
