Baxi Boilers Review
A review of Baxi boilers used for space and potable water
heating. Comparison of system, combi and heat-only boilers, features
and specs of the most advanced models in UK.
Baxi boilers manufacturer is the UK based company that is part
of BDR Thermea (based in Netherlands), and is one of the most popular
brands in Europe, especially in UK, Holland, Spain and Italy. Baxi
offers a decent number of high performing combi and conventional
gas-powered boilers, including heat only type, all small in size and
with the compact, wall-mount and space saving design. All the models
are fan-assisted for a safe operation and utilize condensing
technology for an increased efficiency.
Even small in size, Baxi high efficient boilers are able to
generate less or more power covering from small to large
homes. Small size (for example Baxi Duo-tec
models comes in size of 780 x 450 x 345mm) allows easy handling and
wall-mount
installation.
Baxi combi boilers
Baxi combi or combination boilers are the most
popular type
due to its versatility; delivering hot water not only for showers or
dishes, but also for central heating.
As opposed to the heat-only
boilers, combi and system boilers have the expansion tank and
circulation pump already built-in, which makes the installation
quicker. Combi boilers generate hot water on demand and do not require
water tank or a cylinder.
Combi boilers from Baxi are available in several groups all
considered as high efficiency;
- EcoBlue Advance Combi
- Platinum
- EcoBlue + Combi
- Baxi Duo-tec
- MainEco Combi
Baxi EcoBlue Advance and Baxi Platinum
series come with the capacities ranging from 24kW to 40kW, where the
maximum water flow rate is in the range from 10 litres per minute to
16.4 l/min, which guarantees enough hot water from smaller to mid-sized
homes. Both groups come with the longest warranty Baxi offers, 10
years.
The Baxi EcoBlue Advance is more
advanced; it has the higher efficiency (max. 90% vs. max. 84% on Platinum),
it's advanced control panel consists of the control touch buttons, big
LCD display, while the Platinum group uses the
selector knobs with the smaller and simpler LCD display and LED status
lights. The Platinum models are quieter when
comparing the sound levels and also include the 24-hr mechanical timer
as a standard equipment, while it is optional on the Advance
models.
The EcoBlue + Combi is available in
three models,where the 33kW is the most powerful, providing up to 13.5
l/min of hot water, in domestic hot water heating mode. Baxi Due-tec
series also includes one large 40kW model on natural gas, and one 28kW
model that operates on propane gas. The warranty of both groups is 7
years, which is shorter than the warranty found on the Advance
series.
Every combi boiler has the boiler controls hidden under the
front lid allowing to turn the unit ON or OFF, control the heating
mode, adjust the water temperature, show the information (i.e. status,
temperature, error code) on the small display, visually check the
pressure on pressure gauge and install the mechanical or digital timer
in the empty slot (standard on Platinum models).
The Baxi MainEco Combi is a group of 3
models with the largest unit of 35kw, all designed simple, but
efficient, where the most powerful unit is capable of providing hot
water with the maximum water flow rate of 14.5l/min. The warranty of 3
years makes it the shortest of all combi units.
Baxi system boilers
Baxi boilers are also designed for combined hot water
production and space heating utilizing the hot water cylinders. These
are known as the Baxi system boilers, and as the combi type, expansion
tank and the circulation pump are factory built-in.
There are several models available:
- EcoBlue System
- MainEco System
- Megaflow System
The EcoBlue series comes in six
different sizes, from the lowest 12kw to the highest 32kW, suited from
small to large houses. All models come with the warranty of 5 years.
This is also the most advance and efficient boiler in this group.
The MainEco series of Baxi system
boilers has the shortest warranty of 3 years and are available in two
capacities of 18 and 24kW, both suitable for homes that lack in space.
As opposed to the previous model,which is equipped with the durable
stainless steel heat exchanger, the MainEco
series utilize the lightweight aluminum heat exchanger, which is also
resistant to corrosion.
The Megaflow series is used in larger
homes with the high hot water demand. It comes in 5 models, where the
largest one is 32kW, and the warranty is the longest of all previous
categories, 7 years. As the MainEco series, the
control knobs are there for temperature adjustment, also a small
display with the LED diagnostic indicators.
Baxi heat only
The smallest and lightest group of Baxi boilers are the EcoBlue
Heat, Advance Heat and MainEco
Heat series, all designed for potable water heating only.
These are coupled with the conventional or solar thermal hot water
cylinders and cold water storage tanks, providing sufficient hot water
even for large homes with multiple bathrooms.
The EcoBlue Heat and the Advance
Heat are comprised of 5 sizes each; from 12 to 24kw, and
from 13 to 30kW, while the MainEco has 3 models
from 15kw to 24kW.
These units do not have the pump and expansion vessel, and the
heat exchanger is made of lightweight aluminum. These units save lots
of energy due to its high efficiency and are suitable for indoor
installation as the noise level is very low. The EcoBlue Heat
models carry the warranty of 2 years while the Advance Heat
models have longer warranty of 5 years. Another difference is the
option to install a top or rear flue for the Advance Heat
group while the EcoBlue group has the top central
flue option only. Both have a simple rotary button at the bottom for
temperature adjustment and indicator LED lights for the operating
status and fault diagnosis.
