Price: $1,140 Delivered

Installation Sequence:

1. Preparing a brick or cement foundation next to the hot tub to receive the Chofu heater.

2. Cutting 1 7/8-inch holes in the side of the tub wall for thru-wall ports.

3. Installing pipes to connect heater and tub.

4. Installing the stove pipe, (8 feet recommended)

Operations

The Chofu heats water on-demand, the day it is needed. (It does not have a thermostat). The heater is operated manually with an automatic ignition switch, however, it uses a spring wound timer to control the duration of heating and to automatically turn off the heater. The main control switch for the heater is designed to be mounted on the side of the tub, for easy access in or out of the tub. If water in the tub looses too much heat while it’s being used, it can quickly be brought up to temperature without having to step out of the tub.

Heating

The Chofu puts out 30,000BTU’s. A 200-gallon tub can be heated at approx. 20ºF per hour. 55ºF to 105ºF

Filter System Option

The Chofu system will be attractive to customers who have limited electrical capacity at their cottage or would not frequent the hot tub on a daily basis (weekend use). As an option we offer a low voltage filter/pump system with a GFI receptacle. This system, with proper chemical maintenance, allows users to extend the clarity and "health" of the water allowing an extended time frame between draining of the tub.
