[Digestion] Digestion] Water Heaters Kenya

Mon Aug 6 14:23:52 CDT 2012

Greetings Kyle, 

This is a good question, which I get regularly, First point

*       Water heating takes allot of energy - having enough energy to heat
water and cook food in a house hold, from my experience is a stretch. 

*       When I have installed this system I have used a hybrid heating
system and it has a electric water heater cylinder with the thermostat set
high with,

o      Biogas instant water heater - feeding the electric water heater
cylinder

o      Solar water heater - feeding the electric water heater cylinder

o      Wet back wood fire - feeding the electric water heater cylinder

*       And I am also using domestic biomass gasifier to top up the gas when
needed. As I run my system on a hybrid gas, syngas (producer gas) and biogas

I hope this is helpful

Dear Digestion List

First let me introduce myself to the list. I have just recently joined and

have enjoyed the emails I receive on a daily basis.

I am the owner of a biogas company in Kenya called Takamoto Biogas and we

have been in operation for almost a year and have really enjoyed the work.

We build for clients from 6 cubic meters to 100 cubic meters and are

looking into large capacity systems as well. We also build Anaerobic

Baffled Reactors for human waste.

I am looking for leads on biogas fired water heaters with a storage

capacity of 100 litres or so. I have seen the instant water heaters on

alibaba.com but my client is looking to heat water for his whole house.

Does anyone know where I can get such water heaters? If not, how can I

convert a natural gas or LPG water heater to run on biogas? Is there

anything I should know?

All the best wishes,

Kyle

Kyle,

I have been using the Hugo Junkers model of point of use water heater for
years. Much more hot water, less trouble.
http://www.bosch.com.mx/content/language2/html/2503.htm Nat gas models work
fine for most biogas out of the box

Water pressure is the only requirement. 3Mt column of water for most models

Hi Kyle,

In Mexico, domestic water heating is a really common use of biogas.  We have
two strategies. First, using a boiler designed to receive woodfuel that is
available everywhere in local markets.  It essentially has the water heating
tank with a combustion chamber below where we mount a biogas burner.  Or we
will use an lp gas boiler, and either remove the burner equipment or just
the pressure regulators.  These are both very low cost options and work
really well.  

Downsides are that they do not use a pilot flame, and should be lit ahead of
use.  Also, the tanks are much smaller than 1000 liters (big water tank!),
generally between 60-100 liters.  The benefit of the smaller tank is that
you heat water quickly, and it functions in some ways as "on-demand" as it
will give constant hot water as long as the gas is on.  

>From our experience, you cannot use lp gas or nat gas boilers out of the box
for domestic biogas use.  They require too much pressure and do not deliver
enough gas volume.
