Energy sav­ing

Energy sav­ing for heat­ing and cool­ing sys­tems.

For a hous­ing com­pany (res­id­en­tial prop­erty), heat­ing energy is usu­ally the largest single cost. In industry, cool­ing capa­city determ­ines wheth­er the pro­cess keeps run­ning. When the water or heat trans­fer flu­id in the net­work becomes dirty, the sys­tem has to work harder to achieve the same res­ult.

Ves­iTekno helps prop­er­ties and industry reduce energy costs and extend the ser­vice life of their sys­tems. We restore the per­form­ance of heat­ing and cool­ing net­works with pro­fes­sion­al clean­ing, flush­ing and optim­isa­tion ser­vices. We have almost 30 years of exper­i­ence and more than 1,500 com­pleted pro­jects.

How can you tell that a sys­tem is wast­ing energy?

Heat­ing and cool­ing sys­tems often waste energy long before an actu­al fault is detec­ted. Impur­it­ies, air, sed­i­ment and limes­cale depos­its impair heat trans­fer and force the sys­tem to run at a high­er out­put than nor­mal.

Heat­ing sys­temCool­ing sys­tem
Typ­ic­al signsThe heat­ing net­work gives off heat poorly, radi­at­ors per­form poorly, room tem­per­at­ures are unevenInsuf­fi­cient cool­ing capa­city, chilled beams per­form poorly, the con­di­tion of the glycol or oth­er heat trans­fer flu­id has not been checked for a long time
Most com­mon causeDirt, sed­i­ment and mag­netite accu­mu­lated in the net­workImpur­it­ies accu­mu­lated in the net­work and aged heat trans­fer flu­id
Con­sequencesEnergy con­sump­tion rises and indoor con­di­tions deteri­or­ateEnergy con­sump­tion rises, equip­ment is put under strain and pro­cess reli­ab­il­ity declines
Solu­tionClean­ing the net­work with Eco­boost clean­ing solu­tion, flush­ing and, if needed, installing a fil­terClean­ing and flush­ing the net­work, repla­cing the flu­id and thor­ough vent­ing

Signs that apply to both sys­tems

  • Increased energy con­sump­tion with no clear reas­on
  • Air prob­lems and flow noise in the net­work
  • Recur­ring alarms, fault noti­fic­a­tions or pump prob­lems
  • Dirty strain­ers, fil­ters and heat exchangers
  • Sludge, limes­cale or iron sed­i­ment accu­mu­lated in the net­work

The longer impur­it­ies are allowed to build up, the high­er energy costs rise and the more expens­ive repairs become. Ves­iTekno assesses the con­di­tion of the sys­tem, cleans the net­work and optim­ises its oper­a­tion. The res­ult is a more energy-effi­cient, more reli­able and longer-last­ing sys­tem.

Dirt, sludge and air in the net­work: how we remove them

Reduced out­put and rising energy con­sump­tion often have the same cause: a dirty net­work or aged flu­id. This is how we resolve the two most com­mon situ­ations.

Prob­lem: dirt, sed­i­ment and mag­netite build­ing up in the heat­ing net­work impair heat trans­fer and increase energy con­sump­tion.

Solu­tion: we clean the net­work with Eco­boost clean­ing solu­tion and flush it free of impur­it­ies. At the same time, we can install a fil­tra­tion solu­tion that pre­vents new dirt from build­ing up.

Res­ult: optim­ising the heat­ing net­work is one of the most cost-effect­ive ways to reduce a property’s energy costs. Liv­ing com­fort also improves when indoor con­di­tions are even and pleas­ant through­out the prop­erty.

Prob­lem: when impur­it­ies build up in the cool­ing net­work and the heat trans­fer flu­id ages, cool­ing capa­city declines and energy con­sump­tion rises.

Solu­tion: we clean and flush the sys­tem, replace the flu­id and vent the net­work thor­oughly.

Res­ult: repla­cing the solu­tion can bring sig­ni­fic­ant energy sav­ings and restore the system’s ori­gin­al per­form­ance. It also reduces the risk of cor­ro­sion and mal­func­tions and extends the ser­vice life of the equip­ment.

Fil­tra­tion keeps the net­work clean

To clean heat­ing and cool­ing net­works, we use, for example:

  • Hei­fi-Top air and dirt sep­ar­at­ors, which con­tinu­ously remove air and impur­it­ies from the sys­tem
  • Fer­roclean mag­net­ic fil­ters, which effi­ciently cap­ture iron sed­i­ment and mag­netite.

How does clean­ing bene­fit the cus­tom­er?

A clean, prop­erly func­tion­ing net­work shows both in the energy bill and in every­day oper­a­tion:

  • bet­ter heat­ing and cool­ing per­form­ance
  • lower energy con­sump­tion
  • more even con­di­tions in the prop­erty
  • few­er mal­func­tions and repairs
  • a longer ser­vice life for the sys­tem.

This is how Ves­iTekno helps restore the energy effi­ciency and reli­ab­il­ity of net­works for the long term.

Heat trans­fer flu­id affects energy con­sump­tion

Heat trans­fer flu­id car­ries heat and cold through the net­work and pro­tects the sys­tem against freez­ing and cor­ro­sion. When the flu­id ages or becomes dirty, heat trans­fer weak­ens and the sys­tem con­sumes more energy to achieve the same res­ult.

A cor­rectly selec­ted flu­id in good con­di­tion keeps energy con­sump­tion under con­trol and extends the ser­vice life of the sys­tem. Ves­iTekno man­u­fac­tures and sup­plies heat trans­fer flu­ids for prop­erty and indus­tri­al applic­a­tions and mon­it­ors their con­di­tion.

How we look after the flu­id

We check the con­cen­tra­tion, freez­ing point, pH value and gen­er­al con­di­tion of the heat trans­fer flu­id. If neces­sary, samples are ana­lysed at MetropoliLab’s accred­ited labor­at­ory. Based on the res­ults, we carry out the neces­sary work:

  • clean­ing and flush­ing the sys­tem
  • repla­cing the glycol or heat trans­fer flu­id
  • filling and top­ping up
  • vent­ing and com­mis­sion­ing
  • ongo­ing ser­vi­cing and main­ten­ance.

Our range includes ethyl­ene and pro­pyl­ene gly­cols, ECO FROST®, Naturet® eth­an­ol solu­tions, GEO Frost® flu­ids for geo­therm­al bore­holes, and brines for ice rinks and tracks.

How the ser­vice works

01

Con­di­tion inspec­tion

We assess the cur­rent con­di­tion of the sys­tem and the flu­id.

02

Ana­lys­is

Water and flu­id samples are tested in a labor­at­ory.

03

Actions

Clean­ing, flush­ing, flu­id replace­ment, filling and vent­ing, plus fil­ter install­a­tion where needed.

04

Optim­isa­tion

We adjust the sys­tem to run cor­rectly with the low­est pos­sible energy con­sump­tion.

05

Ongo­ing main­ten­ance

We agree a ser­vice inter­val so that the res­ults last.

Who is the ser­vice for?

We serve hous­ing com­pan­ies, prop­erty main­ten­ance com­pan­ies, con­struc­tion com­pan­ies and private indi­vidu­als, as well as demand­ing indus­tri­al sites. These include data centres, the paper and food indus­tries, the pro­cess industry, indoor and out­door ice rinks, and freez­ing plants.

The Amazo­nia house at Korkeas­aari

In the Amazo­nia house at Korkeas­aari, the well­being of anim­als that need trop­ic­al con­di­tions depends on prop­erly func­tion­ing water and heat­ing sys­tems. Ves­iTekno cleaned and upgraded the building’s water net­works and looks after their ser­vi­cing and main­ten­ance. The aim was to improve the energy effi­ciency of the sys­tems.

What does energy sav­ing mean in prac­tice?

In apart­ment build­ing heat­ing, energy sav­ings of up to 4–7% have been achieved. The sav­ings do not show only in the energy bill. A clean, cor­rectly adjus­ted sys­tem also brings:

Lower energy costs

Few­er mal­func­tions and repairs

A longer ser­vice life for the sys­tem

Lower energy costs

Fre­quently asked ques­tions

Yes. We also help when we were not involved in the ori­gin­al install­a­tion of the sys­tem.

The gen­er­al recom­mend­a­tion is at least once a year. Demand­ing indus­tri­al sites may need more fre­quent inspec­tions.

We oper­ate through­out Fin­land.
